Interpretation Introduction

(a)

Interpretation:

The symbol of element should be identified for $1s^{2}2s^{2}2p^{6}3s^{2}3p^3$ electronic configuration by using periodic table.

Concept Introduction:

The distribution of electrons in atom into orbitals is said to be electronic configuration. The electronic configuration for every element present in the periodic table is unique or different. Atomic number is equal to the number of protons, which is further equal to the number of electrons for neutral atom.

The electronic configuration can also be written as abbreviated configuration. Abbreviated electronic configuration is defined as the electronic configuration of the forgoing or previous noble gas is replaced by writing the symbol of element inside the square brackets.

Periodic Table contains periods and groups. There are 18 groups and 7 periods in the periodic table. The vertical columns are known as groups and horizontal rows are known as periods. The numbering of periods is done as 1 to 7 from top to bottom and groups are named as 1A, 2A, 3B to 8B, 1B, 2B, 3A to 8A from left to right where A represents representative elements and B represents transition elements.

In periodic table, different blocks within the periodic table correspond to the s, p, d and f sublevels. Thus, on the basis of increasing atomic number in the periodic table, electronic configuration of atoms can be written.

Interpretation Introduction

(b)

Interpretation:

The symbol of element should be identified for $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^7$ electronic configuration by using periodic table.
