Chapter 5.4, Problem 37PP

(a)

Interpretation Introduction

Interpretation:

The symbol of element should be written with $1s^{2}2s^1$ electronic configuration.

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.

(b)

Interpretation Introduction

Interpretation:

The symbol of element should be written with $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^2$ electronic configuration.

(c)

Interpretation Introduction

Interpretation:

The symbol of element should be written with $[Ar]4s^{2}3d^{10}4p^2$ abbreviated electronic configuration.
