New cards

Octet rule

Most atoms are stable with 8 valence electrons and atoms will donate, steal of share electrons to achieve this

3
New cards

Octet rule exceptions

  • H is stable with 2 electrons

  • B tends to be more stable with 6 electrons

  • Non-metals with 3 or more energy levels can sometimes have MORE than 8 valence electrons
