Chapter 9, Problem 70E

Interpretation Introduction

Interpretation: The number of $\text{3}d$ electrons for each element is to be given.

Concept Introduction:

The illustration of the orbital occupation by electrons in an atom is known as electron

configuration.

Periodic table is the arrangement of elements in rows and columns according to their

atomic numbers.

The rows in the periodic table are known as periods and the columns are known as

groups.

The periods are specified by the outermost principal shell occupied by the elements in it.

The elements in a group have equal number of valence electrons.

The number of electrons that occupy various orbitals is: $s\to 2;p\to 6;d\to 10;f\to 14$
