Ionic, Covelant and Metallic Bonds
A Love Story
Elements just want to feel complete, so they strive to form bonds with other chemicals so they both can feel satisfaction. The main point of interest is whether they pass off electrons to each other or they share electrons.
IONIC BONDS - Ionic Bonds lose or gain electrons to form compounds. This also means that it must be a pairing of a metal and a nonmetal. Salt is an example of this because Na is a metal and Cl is a nonmetal.
COVELANT BONDS - Covelant bonds share electrons to fill their outermost shell. This can only occur between either two metals or two nonmetals. If the two metals are the same, it is no longer a covelant bond but a METALLIC BOND. As an example, H2 is covelant BUT Fe2 would be metallic. Easy enough, right?
There are some great ways to determine which is which. If the element appears shiny, you know it's metallic and if it's powdery or grainy it's ionic or covelant. Ionic bonds are soluble, metallic bonds aren't, and covelant is a wild card in that respect. Covelant bonds can melt but only they can. Metallic bonds can conduct as a solid or a liquid, Ionic bonds can conduct as a liquid or in a dissolved form, and Covelant bonds can't conduct diddly squat.
And thus, the bonds all lived happily ever after. Except for the Noble Gases.
