It wants to obtain or share one.
you need two atoms depending how many electrons they want to get or get rid of like water hydrogen wants to give away one electron and oxygen wants to get two electrons that is how it becomes H2O
Al2O3, each formula unit would have 6 shared electrons. Al wants 3 electrons per atom and O can give 2 electrons per atom.
carbon
When the valence (outer) shell has 5 or more electrons, excluding 8, including hydrogen, being more reactive when there are more electrons. This is because the atom wants to have 8 electrons in its outer shell (hydrogen wants 2), so those with 8 electrons don't want to react, while those with 7 REALLY want to react.
It wants one.
every element wants to fill the outer shell. That means if it is at 5 electrons it wants to get to 8. If it is at 3, it wants to get to 0.
Phosphorus wants to gain three electrons to have 8 valence electrons.

Phosphorus wants to gain three electrons to have 8 valence electrons.
8 - called valence electrons. it doesn't matter what energy level or orbital shape. a "happy atom" has 8 valence electrons

Bromine want an electron.

Carbon needs 4 valence electrons to satisfy it's outer energy level.
Al2O3, each formula unit would have 6 shared electrons. Al wants 3 electrons per atom and O can give 2 electrons per atom.
Carbon, as a non-metal wants to gain electrons to have 8 outer shell electrons. In its outer shell, carbon has 4 electrons. Therefore, a carbon ion picks up 4 electrons to become C-4
