(a)

Interpretation Introduction

Interpretation:

Based on the given electronic configurations, the corresponding metal or ion has to be identified.

Concept Introduction:

Electronic configuration:

The electronic configuration means the distribution of electrons in the atomic or molecular orbitals.

Electronic configuration of a metal atom or ions means the distribution of electrons in the atomic orbitals of a metal atom or ion.

The symbols in the electronic configuration of atomic orbitals are:

$\left[\text{He}\right]$ is called the helium core and it represents the electronic configuration ${\text{1s}}^{\text{2}}$

$\left[\text{Ne}\right]$ is called the neon core and it represents the electronic configuration ${\text{1s}}^{\text{2}}{\text{2s}}^2{\text{2p}}^6$

$\left[\text{Ar}\right]$ is called the argon core and it represents the electronic configuration $\left[\text{Ne}\right]{\text{3s}}^2{\text{3p}}^6$

$\left[\text{Kr}\right]$ is called the krypton core and it represents the electronic configuration $\left[\text{Ar}\right]{\text{4s}}^{\text{2}}{\text{3d}}^{10}{\text{4p}}^6$

$\left[\text{Xe}\right]$ is called the xenon core and it represents the electronic configuration $\left[\text{Kr}\right]{\text{5s}}^{\text{2}}{\text{4d}}^{10}{\text{5p}}^6$

$\left[\text{Rn}\right]$ is called the radon core and it represents the electronic configuration $\left[\text{Xe}\right]{\text{6s}}^{\text{2}}{\text{4f}}^{14}{\text{5d}}^{10}{\text{5p}}^6$
