Expanding Octets

Expanding Octets

• Elements from period 3 and beyond can expand their octets.
• Phosphorus is the correct answer because it can have more than 8 electrons around it when forming covalent bonds.
• The other options are incorrect:
  • Magnesium does not form covalent bonds.
  • Silicon does not necessarily need to expand its octet.
  • Chlorine typically will not expand its octet.
