100
What is a monoatomic ion?
an ion consisting of a single atom with a positive or negative charge resulting from the loss or gain of one or more valence electrons, respectively.
100
What is a binary compound?
a compound composed of two elements that can be either ionic or molecular
100
When the name of the anion ends in -ide and there is no oxygen present, the acid name begins with the prefix ______ the stem of the anion has the suffix _____, and is followed by the word acid.
hydro, -ic
100
The name for NO
Nitrogen monoxide
100
Chemical formula for phosphorus pentahydride
PH5
200
What is a polyatomic ion?
An ion composed of more than one atom
200
To name any binary ionic compound, place the ______ name first, followed by the ______ name.
cation, anion
200
When the anion name ends in -ite, the acid name is the stem of the anion with the suffix _____, followed by the word acid.
-ous
200
What is the chemical formula for barium fluoride?
BaF2
200
Chemical formula for iron (II) oxide
FeO
300
Which type of element ends in ide?
A nonmetal
300
Why is it necessary to write a Roman numeral after the element name for a transition metal?
The number of electrons lost by a transition metal is not as easy to predict.
300
When the anion name ends in -ate, the acid name is the stem of the anion with the suffix ____ followed by the word acid.
-ic
300
An -ite or -ate ending means a polyatomic ion that includes _______ in its formula
oxygen
300
Name HClO3
Chloride acid
400
The charges of cations of many transition metal ions must be determined from the number of _____ lost
electrons
400
Why don't you need to use prefixes when writing down the names for simple ionic charges?
You already know the charges of the metals and nonmetals and you know that the charges have to add up to zero.
400
Why aren't parentheses needed when naming oxyacids?
Only one polyatomic ion is present.
400
Name Ni3(PO4)2
Nickel (II) phosphate
400
Find the formula for copper (I) phosphite
Cu3PO3
500
The names of most polyatomic anions end in ____ or ____.
-ite, -ate
500
When writing the chemical formula for an ionic compound with the transition metal, how do you know which Roman numeral to use?
You figure out the total negative charge, then figure out the total positive charge, then average that charge.
500
When the prefix is per, what is the pattern?
four oxygen atoms
500
Name HClO
Hypochlorous acid
500
Name the compounds CuBr2, SCl2, BaF2. Explain the use or omission of the Roman numeral (II) and the prefix di-
CuBr2 Copper(II) bromide *roman numeral is used when there is a transition metal (Cu) SCl2 Sulfur dichloride *"di-" is used when there are two nonmetals paired BaF2 Barium fluoride *this does not have "di-" because it is a metal and a nonmetal
