Question

how do the following properties change in a period and group ?
i.) atomic radius ii.)ionization capacity
iii.) electronegativity iv.) electropositivity

Answer 1

$\huge\mathbb\red{Answer:-}$

Atomic Radius ::

➡ The Atomic Radius Increases From Top to bottom .in Group

➡Atomic Radius Decreases Along the period .

➡This Same in Electro positivity

Ionisation Enthalpy ::

➡ionisation Enthalpy Decreses In the Group

➡Ionisation Enthalpy Increases along Period .

➡This is same in Electro Negativity .

Hope it helps u dear ☺❤

Answer 2

Atomic Radius ::

➡ The Atomic Radius IncreasesFrom Top to bottom .in Group

➡Atomic Radius Decreases Alongthe period .

➡This Same in Electro positivity

Ionisation Enthalpy ::

➡ionisation Enthalpy Decreses Inthe Group

➡Ionisation Enthalpy Increasesalong Period .

➡This is same in Electro Negativity.

hope this helps..☺
