Why do different molecules have different bonds?
2 years ago
OpenStudy (brownleanna1223):
Molecules have different because of the way the molecules are bonded. A metallic bond is formed from the bonding between two metals. Ionic bonds are formed from the transfer of electrons and covalent bonds are formed from the sharing of electrons. There are two types of covalent bonding: polar and non polar. A polar covalent bond is formed when a pair of electrons is unequally shared between two atoms and non polar is when they are equally shared. You can also tell is it's polar or non polar by the electronegativity difference. If the electronegativity difference is 0, it is non polar, if it's greater than 0 but less than 2.0 it is polar. Hope this helped :)
