Question | Answer |
compound made from transfer of valence electrons | ionic |
compound made from sharing of valence electrons | covalent |
Need this for knowing charge of D block elements | Roman Numeral |
charge of cations | positive |
charge of anions | negative |
prefix for 10 | deca |
prefix never used on first anion in a compound | mono |
prefix for 9 | nona |
sharing 2 total valence electrons | single covalent bond |
sharing 6 total valence electrons | triple covalent bond |
sharing of 4 total valence electrons | double covalent bond |
this trait determines the "tug of war" over shared electrons | electronegativity |
charge of both ionic and covalent compounds | neutral |
neutral group of atoms joined with covalent bonds | molecule |
equal sharing of valence electrons | nonpolar covalent bonding |
unequal sharing of valence electrons | polar covalent bonding |
2 ions in an ionic bond | cation & anion |
2 ions in an covalent bond | anion & anion |
says that atoms and ions become stable with 8 valence electrons | octet rule |
name of ions specifically from group 7A | halide |
element that is the exception in group 8A due to # of valence electrons | He |
element that will always win the "tug of war" for shared electrons | F |
group that halide ions come from | 7A |
group's electron configuration is the goal of covalent and ionic bonding | 8A |
charge of ionic and covalent compounds | neutral |
prefix for 8 | octa |
prefix for 6 | hexa |
prefix for 7 | hepta |
the number of valence electrons matches this number | group |
2 ways of finding the chemical formula of a covalent compound | Lewis dots & prefixes |
2 ways of finding the chemical formula of an ionic compound | Lewis dots & criss crossing |
bond when 1 element provides both shared electrons | coordinate covalent |
cations are in these groups | 1A , 2A , 3A |
anions are in these groups | 5A , 6A , 7A |
