Question #e76f5

Answer 1

They are called a molecule.

Explanation:

Molecules are composed of two or more atoms covalently bonded, which means the sharing of valence electrons. Generally molecules are formed from nonmetals. A single covalent bond forms from the sharing of two valence electrons between atoms. A double covalent bond is formed from the sharing of four valence electrons between atoms, and a triple covalent bond is formed from the sharing of six electrons between atoms.

The hydrogen molecule `("H"_2")` is composed of a single covalent bond in which the valence electrons are shared.

The water molecule `("H"_2"O")` is composed of two single covalent bonds between the hydrogen atoms and the oxygen atom.

The oxygen molecule `("O"_2")` is formed by the formation of a double covalent bond between atoms. Four electrons are shared instead of two.

The nitrogen molecule `("N"_2")` is formed by the formation of a triple covalent bond between atoms. Six electrons are shared.
