Class 11

There are a total of 36 questions comprising 14 straightforward formula-based sums, 16 challenging problems, and 6 intermediate.

An expression with two terms raised to a positive integer power can be expanded in Maths, such as (a + b)? This algebraic rule is known as the Binomial Theorem. 

The three fundamental laws of chemistry are - Law of Definite Proportions, Law of Conservation of Mass, and Law of Multiple Proportions.

The three types of chemical bonds are - ionic, metallic and covalent bonds. When the electrons transfer between the atoms, they form the Ionic bonds by producing charged ions that are attracted to each other. When atoms share electrons, covalent bonds are created. When metal atoms share a sea of delocalized electrons, metallic bonds get created.

The chemical bonds can be primary or strong bonds such as ionic, covalent, and metallic bonds. It can also be the secondary or weak bonds like hydrogen bonding, London dispersion force, and dipole interactions.

It is the bond that holds the ions, atoms or molecules to form stable substances, compounds and larger structures.

In Chemistry, the bonds are of four types - Covalent bond, Ionic bond, Hydrogen bond, and Metallic bond.

The different types of sets covered in this chapter are - Empty Set, Singleton Set, Finite Set, Infinite Set, Equal Sets, Equivalent Sets, Subset, Proper Subset, Universal Set, Power Set, and Disjoint Sets.

Union (? ) in sets means "or". It gives a set of all unique elements of two or more sets. Intersection (? ) means "and". It includes all the common elements of two or more sets.

Mathematics in Class 11 is considered tough as compared to Class 10 as it marks a notable leap in the abstractness and complexity. However, regular practice can help you to master the Maths Class 11 including the chapter 1 sets.
