Question
Chapter 5, Problem 5ST
Interpretation Introduction
Interpretation:
The atomic radius of selenium is to be predicted.
Concept Introduction:
The distance present between the nucleus and the valence shell electrons of an atom is known to be the atomic size or atomic radius of that atom. On moving along the period in a periodic table, the number of orbital remains same and a new electron is added to the same orbit. As a result, the atomic radius of elements decreases along the period.
