Ionic bonds and Binary ionic bonds

What is an ionic bond?

Chemical bond formed by transfer of electrons from a metal to a non-metal, making positively charged cations and negatively charged anions

Why do ionic bonds form?

To have a full outer electrons shell and create stable electron configurations

What is a Binary ionic compound

Compound made of two elements, a metal cation and non-metal anion bonded by ionic bonds

How are binary ionic compounds formed?

Through the transfer of electrons from metal to non metal to satisy octet rule

What types of elements typically form ionic bonds?

Metals and non-metals

What ions do Group 1 and 2 elements form?

Group 1, +1
Group 2, +2

What ions do Groups 15-17 form?

Group 15, -3
Group 16, -2
Group 17, -1

Why use Roman numerals in some ionic names?

Show charge of transition metals

Properties of ionic compounds?

High melting/boiling point
solid/crystaline
conducts electricity in solution
Brittle
