Ionic vs Covalent

Review of Ionic and Covalent Compounds

QuestionAnswer
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
