3.3.2 Bhasa2p energy level: 2p has a higher energy than 2s. ~
Therefore less energy is needed to remove the valence electrons from B as
from Bev v.
B het 'n 2p energieviak; 2p het meer energie as 25 “
Dus minder energie word benodig om 'n valenselektron van B te verwyder in
vergelyking met Be. “~

OR/OF

2s electrons are paired and 2p electron is unpaired. “ Therefore, less energy
needed to remove 2p electron. vv

Die 2s elektrone is gepaard teenoor die ongepaarde 2p elektrone. V Daarom
word minder energie benodig om 'n 2p elektron te verwyder, vv

OR/OF

The 2p electron is further away from the nucleus v. Therefore, the
electrostatic force weaker and requires less energy. vv

Die 2p electron is verder van die kernv, dus is die elektrostatiese krag
swakker en daarom word minder energie benodig om die elektron te
