Chapter 8, Problem 8.22QP

Interpretation Introduction

Interpretation:

The element from which the given ion is derived has to be identified.

Concept Introduction:

• Atomic number is the total number of electrons or protons that is present in the atom.  Every element has its own atomic number.
• Cation is formed when the electrons are removed from the atom of an element.  As cation is formed by removing electrons, they have a net “+” charge on them.
• Anion is formed when the electrons are added to the atom of an element.  As anion is formed by adding electrons, they have a net “-” charge on them.
• General electronic configuration of elements having electrons in 3d subshell is,

  $1s^2 2s^2 2p^6 3s^2 3p^6 4s^{2}3d^n$
