1
New cards

When can octet expansion occur?

When a p block element has more than 8 electrons in their outer shell

2
New cards

What have more than 8 electrons in their outer shell?

Period 3 onwards

3
New cards

What orbitals do period 3 onwards have?

d orbitals - electrons can enter empty d orbitals allowing the central atom to have more than 8 electrons

4
New cards

What kind of hybridisation occurs when lower orbital electrons enter empty d orbitals?

sp3d2 hybridisation

5
New cards

Explain sp3d2 hybridisation

s and p paired electrons promoted from their ground state to empty 3d orbitals (excited state), giving 6 unpaired electrons available for bonding
