Class 11th Chemistry Chapter 2: Structure of Atom Solution

In this chapter, we will explore the structure of atoms, which are the building blocks of matter. The concept of the atom has evolved over time through various experiments and theories. We will delve into the historical development of atomic models and the contributions of scientists such as J.J. Thomson, Rutherford, and Bohr.

We will start by understanding the basic features of an atom, including its size, mass, and charge. We will learn about subatomic particles, namely protons, neutrons, and electrons, and their properties. The atomic number, mass number, and isotopes will be discussed in detail.

Moving forward, we will study the Bohr’s model of the atom, which explains the arrangement of electrons in different energy levels or shells. We will explore the concepts of energy levels, subshells, and orbitals. The electronic configuration of elements and the periodic table will be introduced.
