What is the rule that elements want to have 8 valence electrons?

• Octet rule

• Octopus rule

• Valence electrons rule

• Ion rule

What advantage does an element have when it has a full valence level of 8 electrons?

• Greater mass

• having more electrons is like having more money

• to over power teh effect of the protons

• stability
