Chapter 3, Problem 87E

Interpretation Introduction

(a)

Interpretation:

The atomic number of ferrum is to be predicted from the periodic table.

Concept introduction:

The elements in the modern periodic table are arranged in an increasing order of their atomic number. In the modern periodic table, the horizontal rows are known as periods, whereas vertical columns are known as groups. There are $7$ periods and $18$ groups in the modern periodic table.
