Why do elements pair together to form compounds?

Answer 1

Apart from the noble gases, all the elements in their natural state are unstable i.e. they don't have stable electronic configuration. In order to gain this stability, they gain or loose

electrons and form ions. This develops an electrostatic force of attraction between ions and they form a bond.

Apart from this, some elements do not loose or gain electrons but share electrons with

other elements in order to become stable and thus form compounds.

Answer 2

Elements form compounds by sharing, gaining, or losing electrons to achieve a stable configuration, usually following the octet rule (having 8 electrons in their outermost shell). This stability is achieved by filling their outer electron shell, which allows them to have a lower energy state and increased stability compared to their individual atoms.

Answer 3

Elements form compounds because elements are usually unstable alone. That is why there are not many elements that occur naturally in a pure form.

Answer 4

The reason is that it makes them chemically stable, or resistent to change.

Answer 5

Because doing so places them in a lower energy state, increasing entropy as per the laws of thermodynamics. In short: because that is how the universe works.

Answer 6

By forming bonds to form compounds, the elements come into a lesser energy level than the existence as the individual state.

Answer 7

Compounds are formed by ionic or covalent bonds between atoms.
