Elements like people are very unstable. They both search though life for their partners. But in the case of elements it can have a max of 4 bonds (maybe Islam got their idea from this!). And once they bonded they stay like that forever unless an outside force caused them to separate. A real life drama.
There are different kinds of bonds: covalent bonds, ionic bonds and metallic bonds.
Covelent Bonds is where elements or atoms share their electrons. Talk about true love…hahaha…
Whereas Ionic Bonds, mostly happens between a metal and a non-metal, where the non-metal gains control of the electron/s and the other giving it up. Hmp, selfish love (non-metal) vs unselfish love (metal)…but this is more common in real life…
Metallic bonds are harder to explain, really techie, but as the name implies it is a bond between metals and usually of the same kind. Homo love...haha...
