Question

which has least I.E 3p3 ,3p6,2p3,2p6​

Answer 1

IE is dependent on following factors:

1. more the value of 'n' less will be the IE as it will be far away from the nucleus, so it will become easy to pull the electron
2. IE will be higher for half or full filled orbitals, bcz by losing electron it will unstable its electronic configuration
3. IE for the subshells are in this order: s>p>d>f
4. bcz more the shell is neare to nucleus more its IE.

so your order will be..

2p6>2p3>3p6>3p3

hope it helps!

Answer 2

Explanation:

IE is dependent on following factors:

more the value of 'n' less will be the IE as it will be far away from the nucleus, so it will become easy to pull the electron

IE will be higher for half or full filled orbitals, bcz by losing electron it will unstable its electronic configuration

IE for the subshells are in this order: s>p>d>f

bcz more the shell is neare to nucleus more its IE.

so your order will be..

2p6>2p3>3p6>3p3
