3.3 Multivalent Metals and Polyatomic Ions Flashcards
Define Multivalent
More than one ion form (possible charge)
Nearly all polyatomic ions contain one or more __ atoms
Oxygen
A polyatomic ion containing two atoms usually has an __ ending.
“ide”
If there are more than two atoms there r generally only __ kinds of atoms and one of them is nearly always __.
two
oxygen
Why is the ending “ate” usually attached to the stem of the first element?
to indicate that oxygen is present
The commonest ion ends in __
“ate”
Define Ternary compounds
Ionic compounds made from more than two elements.
AKA polyaotmic ion compounds
Use __ or a __ when a multivalent metal is in the compound.
prefixes
roman numeral
Ionic compounds start w/ a __ or the __ ion
metal
ammonium
If the compound is covalent, use the __ system
prefix
If the ionic compound ends w/ a single nonmetal, the naming will end in __
“ide”
State the process for naming a metal (single variant) w/ a nonmetal
Name the metal, then the nonmetal w/ the ending “ide”
State the process for naming a metal (multivalent) w/ a nonmetal
Name the metal w/ the valence in bracketed Roman numerals, then the nonmetal w/ the ending “ide”
State the process for naming a nonmetal w/ a nonmetal
Name the first element w/ a prefix (exclude. mono), then the last element w/ prefix and ending “ide”
Name the positive polyatomic ions
NH4^+
H3O^+
