Step 1:Arsenic (EN = 2.18) is less electronegative than oxygen (3.44) soarsenic is the central atom.

You are watching: Aso4 3- polar or nonpolar

Step 2:The total number of valence electrons present in AsO43- is:

Group Valence Electrons

As 5A 1 × 5 e– =5 e–

O 6A 4 × 6 e– =24 e–

From -3 charge: +3e-

Total: 32 valence e–

Step 3:The Lewis Structure is:


Step 4: There are 4 domains or groups around central element As:

4 O atoms= 4 domains

• It will need 4 orbitals to accommodate these 4 groups.

Orbitals that can be used by the central atom:

Subshell Total # of orbitals

s _ 1 orbital

p _ _ _ 3 orbitals

d _ _ _ _ _ 5 orbitals

1 s orbital + 3 p orbitals = 4 orbitals (4 groups)

s p p p = sp3
