Question 26

Compounds features are...

Answer 26

- Compounds are usually a metal and a non-metal. - We name them in 2 parts. 1. The first part of the name is the name of the metal. 2. The second part is the name of the non-metal BUT the ending changes to -ide. MgO- Magnesium oxIDE NaCl-sodium chlorIDE. 3. Ift. the compound contains a metal, a non-metal AND oxygen, it's name ends in -ate. LiNO₃- lithium nitrate CaSO₄- calthium sulfate.
