Let's review some important points

Some text here about the topic of discussion

Compounds can only be Covalent or Ionic

Metals never form compounds by themselves

Compounds are made of two or more different elements bonded together.

​

Compounds therefore have IONIC bonds or Covalent Bonds

​

Metallic bonds form between the atoms in a piece of metal and are usually elements​.

Multiple Choice

Two categories of compounds are

• (1) covalent and molecular

• (2) covalent and metallic

• (3) ionic and molecular

• (4) ionic and metallic

Ionic Compounds have Metals and Non-metals in its structure.

​

Any compound that has both types of Atoms are Ionic Compounds​
