In the fifth chapter, we will learn about the classification of elements and their evolution. The Second unit consists of four chapters that are from sixth to ninth. The sixth chapter is about the various life processes which human need for their survival. In the seventh chapter, we will talk about the parts of the human body which are engaged in control and coordination activities.

The eighth chapter deals with reproduction activities in unicellular and multicellular organisms. The ninth chapter, we will learn how the offsprings look alike. The third unit is How things works which have four chapters. In the tenth chapter, we will learn about light and its phenomena reflection and refraction in a detailed manner.

The eleventh chapter is about the human eye and some optical phenomena in nature. The twelfth chapter deals with the electricity in which we will learn electric circuit and resistance.

In the thirteenth chapter, magnetic effects of electric current and its applications. The fourth unit has three chapters in it.

The fourteenth chapters talk about the various sources of energy such as conventional and non-conventional sources. The fifteenth chapter is about our environment in which we will learn about the eco-systems, food chains and how human activities contribute in degrading its quality.

The last chapter is about the conservation of natural resources. In previous classes, students were introduced to physical and chemical changes. The chemical changes signify the chemical reactions.

The indicators of chemical reactions are explained with some indicators like change in physical state, change in color, change in temperature and evolution of gas. These are explained with some experimental examples. Class 10th chemistry chapter 5 ncert solutions solution that writing of chemical equation has been explained. It is symbolic representation of chemical reactions.

Also, it has been explained that how such equations can be more informative. For example, balancing a chemical equation will signify that the chemical reactions follow law of conservation of mass. Other information like physical states and conditions required for reactions are mentioned. After that class 10th chemistry chapter 5 ncert solutions solution types of chemical reactions are explained are chemstry. The types of chemical reactions are �combination reaction, decomposition soltions, displacement reaction, double decomposition reaction.

On basis of energy, exothermic and endothermic reactions are mentioned. Redox reactions are explained which are combination of reduction reaction and oxidation reaction. All types of reactions are explained with suitable example with their respective chemical equation.

Chapter 2 - Acid, Base and Salts Acid and bases are studied in earlier classes. Acids are defined as substances which are sour in taste and turn blue litmus red. Examples of acids are sour fruits like, Bases are defined as substances which are bitter in taste and turns red litmus blue. Examples of bases are neem, clove, vinegar. Here, acids class 10th chemistry chapter 5 ncert solutions solution bases are defined chemically.

Bases are chemically those substances which generate OH- ions in aqueous solutionIf not they are weak class 10th chemistry chapter 5 ncert solutions solution. After that, various chemical and olfactory indicators are discussed; this indicates the presence of acids or base in the solution.

Bases are said to be strong if whole of them get dissociated in water to form OH- ions. For example, Methyl orange is a chemical indicator. It turns red in acidic solution and yellow in basic cchemistry. Olfactory indicators are indicators which changes odor after coming class 10th chemistry chapter 5 ncert solutions solution contact with acid and base.

For example, smell of clove vanishes class 10th chemistry chapter 5 ncert solutions solution kept in contact with acid. After that acids and bases reactions are discussed with metals, metal oxides and metal carbonates. Reactions between acids and bases are also discussed. They are known as neutralization reactions. Salt is one of the products formed by acid, base reaction. The various types of salts are discussed based on the strength of acid or base.

The pH scale Indicates if the solution is acidic, basic our neutral. It is an scale from So, is acidic, 7 is neutral, basic solution. Universal indicator is a mixture of several indicators.

Chloro-alkali process is performed of salt solution. The various chemical substances dolutions formed after reactions, chqpter or in-directly are used for various process.

Their formation and uses are explained in this chapter. Chapter 3 - Metals and Non-Metals The chapter starts with physical properties chapyer metals and non-metals. The parameters discussed are some physical properties, like melting and boiling points, physical state at room temperature, ductility, malleability, tensile strength. The metals and non �metals are differentiated on the basis of physical properties.

But there are some expectations based on physical properties. For example iodine is non-metal but has lustrous appearance as metal. Mercury is metal but liquid at room temperature. There are more such exceptions. Therefore, classification of metals and non-metals, are based on chemical properties.

Chemical reactions of metals with oxygen class 10th chemistry chapter 5 ncert solutions solution, water, acids and other metal salts are discussed. The chaper and their condition depends upon the reactivity series. The metals on top of reactivity series are sodium and Potassium. They perform vigorous reactions. Nature of metallic oxides is discussed.

Generally Metal oxides are basic in nature. But, some of them like aluminum oxide and zinc oxide can be both acidic and basic and hence known as amphoteric oxides. After that how such reactions takes place is discussed. Ionic bond formation is discussed. Such bond formation can be represented in two forms.

Electrons are loosed by metals and gained by non-metals. One get positively charged and another get negatively charged. They get class 10th chemistry chapter 5 ncert solutions solution and a strong bond is formed. The first one is electronic configuration. The bond formation is discussed through Bohr model.

Another method is Lewis structure or electron-dot structure. The metals and non-metals are written with their classs and dots.

It consists of various to the point question and answers, followed by proper explanations of different subtopics. This solution is what students can avail when they are trying to comprehend the basic concept behind this chapter. This primary knowledge will prove to be useful when a student moves on towards later years of their education.

To understand chemistry as a subject, having a clear concept about elements on the periodic table is necessary. In this segment of chapter 5 science Class 10, students will learn how elements were classified in the periodic table based on their properties.

These elements were segregated from one another on the basis of whether they were gases, metals or non-metals. A German chemist, known to all as Johann Wolfgang Dobereiner, had attempted to group elements based on their properties.

Formation of these groups was known as triads. In this section of the periodic classification of elements in Class 10 solutions, learn about how in this table, every eighth element displays properties that are similar to the first one.

This law may appear in the examination so students will need to memorise it thoroughly. In this section of the periodic classification of elements of class 10 NCERT solutions, an introduction to Mendeleev's periodic table has been provided. In this table, elements were arranged, based on their increasing atomic masses.

This periodic table present in Class 10 Science Chapter 5 NCERT solutions was able to predict the existence of certain elements that back then had not been discovered back then. Hydrogen in this table does not have a fixed position, and Mendeleev also fails to provide any explanation regarding the atomic masses being in the wrong order for some elements.

Elements present in this table of Class 10 Periodic Classification of Elements solutions have been arranged on the basis of their increasing atomic masses. Students will need to learn the order of the elements in this periodic table for their examinations.

This modern periodic table that we find in Class 10 Science Ch 5 solutions, consists of 7 periods and 18 groups. Elements in a period are set on the basis on the maximum number of electrons present. There are different trends in the modern periodic table that have been noticed, which students will learn about in this section.

Electronegativity, electron affinity, metallic character, atomic radius, etc. Here are some of the benefits of availing Class 10th Science chapter 5 solutions from Vedantu -. Go through this page completely to know more about arithmetic series.
