D)INCREASING BOND POLARITY

N - Cl < S-O < As-F < Mg - O

E)DEC. POLARITY OF DIATOMIC MOLECULES

NaCl > HCl > ClF >Cl₂

F)INCREASING ENERGY OF MOLECULAR ORBITALS

*2S <

2P < PI 2PX <

*2P

G)DECREASING SHEILDING EFFECT OF INNER ELECTRONS WITH SAME PRINCIPAL QUANTOM NO.

s > p > d > f

H)DECREASING ENERGY OF ORBITALS

p > sp³ > sp² > sp

I)INCREASING IONISATION POTENTIAL
