atom or group of atoms having a negative charge
anion
compound composed of two different elements
binary compound
sulfur hexafluoride is an example of a
binary compound
atom or group of atoms having a positive charge
cation
what is the correct name for the compound CoCl2
cobalt(II) chloride

dinitrogen pentoxide
The nonmetals in group 6A & 7A
have a numerical charge that is found by subtracting 8 from the group number
a compound composed of a cation and an anion
ionic compound
which set of chemical name and chemical formula for the same compound is correct
iron(III) phosphate, FePO4
which element, when combined with flourine, would most likely form an ionic compound
lithium
when group 2A elements form ions they
lose two electrons
a compound composed of two anions
molecular compound

monatomic ion
which polyatomic ions forms a neutral compound when combined with a group 1A monatomic ion in a 1:1 ratio
nitrate
what is the correct name for the N3- ion
nitride ion
which of the following correctly shows a prefix used in naming binary molecular compounds with its corresponding number
nona- 9
binary molecular compounds are made of two
nonmetallic elements
what type of ions have names ending in -ide
only anions
what does an -ite or -ate ending in a polyatomic ion mean
oxygen is in the formula
tightly-bound group of atoms that behaves as a unit and carries a net charge
polyatomic ion
what type of compound is CuSO4
polyatomic ionic
in naming a binary molecular compound, the number of atoms of each element present in the molecule is indicated by
prefixes
given the name of a binary molecular compound, describe how to write its formula. Use carbon tetrachloride as an example.
prefixes are used when writing the names of binary molecular compounds, such as carbon tetraccloride. The prefix tells how many atoms of an element are present in each molecule of the compound. You then write the symbol an dhte subscript according to the prefixes. Ex: CCl4
