Question | Answer |
overall charge of an ionic compound | neutral |
groups that are cations | 1A , 2A , 3A |
groups that are anions | 5A , 6A, 7A |
ion type that keeps the same name of the element | cation |
ending of the name of all anions | ide |
outside/outermost electrons ; responsible for chemical properties | valence |
change in the number of electrons | ion |
electrons that are closer to the nucleus of atom | core |
Visual representation of valence electrons only | Lewis Dot structure |
the charge of cations | positive |
the charge of anions | negative |
says that atoms of elements need 8 valence electrons to be stable | octet rule |
cations do this with valence electrons | lose them |
anions do this with valence electrons | gain til they have 8 |
compound made between a cation and anion | ionic |
this happens to electrons in ionic bond | transfer from cation to anion |
element already stable with 2 valence electrons | Helium [He] |
elements in this group do not react with others; already stable | 8A / Noble Gases |
the number of valence electrons match this number | group number |
ability to attract electrons from nearby atoms | electronegativity |
name of group 7A ions only | halide |
fastest method to predict formula of ionic compound | criss-cross |
the number of total electrons matches this number | atomic number |
