Chapter 6, Problem 9STP

Interpretation Introduction

Interpretation:

It is to be identified whether Statement I is correct or not. If the statement I is correct explain the reason given is explaining statement I or not.

Concept Introduction :

The electron configuration of an element defines how its electrons are arranged throughout its atomic orbitals. Standard notation is used to represent atomic electron configurations, placing all electron-containing atomic subshells in sequential order. The number of electrons held by the subshell is indicated by superscript.

Answer to Problem 9STP

Statement I and statement II both are incorrect.

Explanation of Solution

When moving from left to right or across the period, electronegativity increases.The left side of the periodic table is often where metals are located, while the right side is where non-metals are located. Therefore, non-metals have a greater electronegativity charge than metals. Metals are electropositive in nature.

Thus, Statement I is incorrect.

Size also decreases across the period or when moves from left to right. Thus, non-metals are shorter in size than metals.

Thus, Statement II is also incorrect.
