Molecular Compounds A2.3

Molecular bonda involve nuclei charing electrons instead of transfer of electrons.

  • Molecular bonds are covalent bonds, non-metals and non-metals

Non-metals hold their electrons much more strongly than metals. Therefore, the bond between the two non- metal elements is not very strong. Because their bonds are weaker, molecular compounds are usually softer than iionic compounds and exist as solids, liquids, or gases. 

All moleular compounds:

  • form between 2 non-metals

  • con be solid, liquid, or gas

  • Attraction between individual atoms in a moleculre is strong, but attraction between neighboring molecules is weak. 

  • Lower metling point

  • Can form crystals like snowflakes

  • Do not conduct electricity

Naming molecular compounds

  1. Write the name for the first element and change the edning of the second element to ide.

  2. Use a prefix to indicate the number of each type of atom.

Ex: P4O10 Is Tetraphosphorous decoxide

Ex: Carbon dioxide: CO2
