Anions- negatively charged ions- these are the ONLY species that form ionic bonds with cations!
An ionic compound contain a cation and an anion.
Lithium. Lithium and hydrogen combine to make lithium hydride, an ionic compound, in which lithium is the cation (positive) and hydrogen is the anion (negative). The cation is always first in the chemical formula for an ionic compound.
A cation is a positive ion and an anion is a negative ion. So the compound you are describing as an ionic one. For example, Cation + Anion --> Ionic Compound Fe3++ O2- --> Fe2O3
Ca(OH)2 is ionic. It is composed of one calcium cation, Ca2+, bonded to two hydroxide anions, OH-.
Covalent. Be is highly electronegative to form ionic bonds.
An ionic compound contain a cation and an anion.
The cation is written first in the chemical formula for a binary ionic compound.
NH4 is the chemical formula of the cation ammonium - (NH4)+.
Lithium. Lithium and hydrogen combine to make lithium hydride, an ionic compound, in which lithium is the cation (positive) and hydrogen is the anion (negative). The cation is always first in the chemical formula for an ionic compound.
Ionic bondVan Der Waals forcesIt is a chemical bondWhen they bond and share and electron, that is a covalent bond.

Can an ionic compound ever consist of a cation-cation or anion- anion bond? Explain.
Can an ionic compound ever consist of a cation-cation or anion- anion bond? Explain.
ionic compounds can desociate into anion & cation.. non ionic compounds can not desociates into anion & cation..
a. cantion on left anion on right.
The chemical formula of sodium chromate is Na2CrO4. The sodium cation is Na+ and the chromate anion is (CrO4)2-.
