Chapter 5.4, Problem 5.40QAP

Interpretation Introduction

(a)

Interpretation:

The symbol of element should be written which has five electrons in 3p sublevel.

Concept Introduction:

The electrons present in atoms are revolving around the nucleus with different energies is known as Bohr Model. Electrons are distributed in the orbitals of the subshell. The specific region of space in which the movement of electrons is confined is said to be shells which are divided into subshells and are s-, p-, d-, and f-. Among these subshells, the electrons are grouped as orbitals.

The number of electrons that these subshells can hold is:

s-block - 2

p-block - 6

d-block - 10

f-block - 14

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.

(b)

Interpretation:

The symbol of element should be written which has four 2p electrons.
