Ionic bonding

Chemists call positively charged ions...

cations

The perfect ionic model states that…

ionic compounds are composed of perfectly spherical cations and anions arranged in a lattice.

Ionic bonding is defined as

the electrostatic attraction between cations and anions

manganate ion

MnO₄^2-

polyatomic ion

when an ion is made up of more than 1 atom

phosphate ion

How do we represent a manganate (VII) ion on paper??

MnO₄^-

The ionic compound which contains Fe3+ and O2− ions is called

iron(III) oxide

Overall, ionic compounds are what charge...

neutral

Ionic compounds are neutral overall, and that means their cations and anions must combine..

in a ratio such that their overall charges cancel each other out
