Ionic Bond Review
Question | Answer |
---|---|
states that 8 is the stable number of valence electrons | octet rule |
element that is the exception to the octet rule (stable with 2) | Helium [He] |
change in the number of electrons | ion |
number that tells the number of ALL electrons | atomic number |
number that tells the number of VALENCE electrons | group number |
fast method of finding formula of ionic compounds | criss crossing |
ion with a positive charge (loses electrons) | cations |
ions with a negative charge (gains electrons) | anions |
overall charge of ionic and covalent compounds | neutral |
cations are found in these groups | 1A, 2A , 3A |
anions are found in these groups | 5A , 6A, 7A |
group(s) not seen in ionic or covalent compounds | 8A |
naming rule for cations | same name as element |
naming rule for anions | ends in "ide" |
