Ionic bonding is when one atom loses an ion to another atom in order to become positively charged and have a full outer shell( either 2 or 8 ions). In a covalent bond two atoms share their outer ions so that both have a full outer shell too. An example of a covalent bond is hydrogen(H2). Hydrogen has only one ion on its outer shell so two hydrogen atoms join together to have a full outer shell of two. Hope this helps!
The compunds is just what is formed like the H2 is now a compound as it is made up of 2hydrogen atoms. Other examples of compounds are carbon dioxide - CO2 hydrochloric acid - HCL (hydrogen and chlorine) hope this helps!!
