Chapter 6, Problem 11STP

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 11STP

Statement I is incorrect, but statement II is correct.

Explanation of Solution

The atomic number of hydrogenis $1$ . Its electronic configuration is,

  $1s^1$

Hydrogen is placed above alkali metal, but it is not a metal.

Thus, the statement I is incorrect.

It is present in group 1 which is present on the left side of the periodic. So, hydrogen is present on the left side of the periodic table.

Thus, statement II is incorrect.
