1398918: your answer is correct

1398918: what tells n+p rule

1398918: because we had law of electron of octet rule

Jabaranki: n=shell no. and p= orbital i.e s,p,d

Jabaranki: are you CBSE board

1398918: and d =?

1398918: no i am in state board

Jabaranki: dont stress now.you will learn it in 11th std
