Atomic Bonding


Atoms connect together forming bonds in two ways: by sharing electrons (covalent) or by steeling electrons (ionic).




The location on the Periodic Table of the atoms in your substance plays a major role in the type of bonding that occurs. Ionic compounds form between metals and non-metals, covalent between two non-metals.


Check your ability to identify ionic and covalent bonds in some common substances in the following activity.

i. ionic
j. ionic



When an atom looses electrons, it is called a cation and gains a positive charge. The atom that gains electrons is called an anion and gains a negative charge.
