Question

On the basic of electronic configuration how will you select 1) the terminating member in a period 2) the chemical similar element

Answer 1

Explanation:

One the basic of electron configuration we can select the terminating number in a period by just seeing the octet configuration.

For example : Neon : 2,8

→ 2 + 8 = 10

so the terminating number for the period is 10.

Similarly,

Agron : 2,8,8

→ 2 + 8 + 8 = 18

18 is the terminating number for this period.

And coming to similar elements,

Atom which have same number of valance electrons have similar chemical properties.

For example : Hydrogen : 1

Sodium : 2,8,1

Potassium : 2,8,8,1

These are chemical similar elements..

HOPE THIS WILL BE HELPFUL

FOR YOU.....

plzzzZz make as breilient answer.....
