Question

Elrctronic confirugation of an atom is 1s2 2s2 2p4 identify group of an atom​

Answer 1

Answer:

Anumber of electrons present in valence shell

of penultimate Shell represents the group of

elements.

For s block elements: no.of group=number of

valence shell electron.

p block elements: no. of group=2+10+number

of valence electrons.

d block elements: no. of group= number(n-1)d

electrons+ number of electrons in nth shell.

Here, the differential electron is in p orbital

hence, it belongs to p block

No. of group= 2+10+3=15 i.e 15th group or V A

group
