The rule that states that atoms tend to form chemical bonds until they have 8 valence electrons.

• octet rule
• rule of eights
• full valence rule
• rule of conservation of electrons
• noble gas rule

What is the diagram demonstrating?

• octet rule
• ionic bonding
• chemical formulas
• noble gas bonding
• chemical reactivity

Why do atoms bond until they are surrounded by eight electrons?

• it gives them full valence electron shells
• it gives them electron configurations like noble gases
• it makes them more stable
• all of the above

Why don't the group 18 noble gases form covalent bonds? (select all that apply)

• they already have 8 valence electrons
• they don't have any unpaired valence electrons
