What elements bond?

I wish I could help, but try to be more specific. There are 117 elements discovered so far... matching them up with all the different combinations is pretty difficult (and would probably take hours! or even days!).

However, I do know that the lower the atomic number, the less ionization energy is required for an element to bond with another. Think about it this way: there are different energy level in each atom. All the atoms "want" 8 electrons in their last level. They could lose electrons or they could gain them. In the families (columns) on the left of the periodic have the elements that would lose one electron, then two in the next family, etc. However, the last families would save more energy by gainingone or two electrons rather then by losing a bunch (That's where the lost electrons go). From there, atoms give away, steal, or share their electrons to be "happy." And that is how they bond.

I hope that helps a little! I know it probably doesn't answer your question, but you can always ask a more specific one if you can't figure it out. Good luck solving that!!
