Here's the scientific definition of what makes a metal as well as how metals are defined according to their position on the Periodic Table.
A covalent bond consists ofthe mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer t...
