Ammonium
NH4+1
When naming ionic compounds, the anions are written first.
False
What is the charge of Group 1A ions?
+1
Covalent compound
Covalent compounds are compounds formed between non-metals only.
Perchlorate
ClO4-1
Almost all polyatomic ions are negatively charged ions
True
Ionic compound
Ionic compounds form when metals and nonmetals exchange electrons
Peroxide
In acids the element hydrogen actually behaves like a Group 1A metal cation. Since it behaves like a +1 cation, hydrogen is always written first in the formulas of all acids. The anion in the acid can be either monatomic or polyatomic, but does not affect how the acid is named.
False- The anion in the acid can be either monatomic or polyatomic, and affects how the acid is named.
