Class 11 Chemistry Chapter 2 Structure of Atom – Important Topics

Atom consists of three subatomic particle – Protons, Neutrons and Electrons.

Protons: These are positively charged particles which are present in the nucleus.
Neutrons: These are neutral particles which are present in the nucleus.
Electrons: These are negatively charged particles which revolve around the nucleus.

Atomic Number of an element is the number of electrons or protons in the atom. The elements in the periodic table are arranged according to the atomic numbers.

Mass Number of an element is the total mass of the nucleon (protons+neutrons) present in an atom. Since electrons are very light, their mass is negligible.

Some of the important atomic models are:

Thomson’s Model
Rutherford Model
Neils Bohr Model

Electrons are filled in orbitals revolving around the nucleon. From lower to higher energy levels, shells are always filled in a step-by-step manner. Electrons aren't filled in following shell until shells before it have been filled.

Electrons in the outermost shell are called valence electrons. These determine the affinity of an element to combine with other elements.
