Chapter 8, Problem 8.86QP

Interpretation Introduction

Interpretation:

The element that forms compounds with every other element in the periodic table except $\text{He}\text{and Ne}$ under appropriate conditions has to be given.

Concept Introduction:

Along the period, the valence electron is added to the same shell and thus attraction by the nucleus gets stronger. Hence, ionization energy increases and reactivity decreases from left to right.

Down the group, the principal quantum number increases from to bottom and thus the size of orbital also increases which results in weak attraction by the nucleus. So reactivity increases down the group.

The periodic table is given below:
