Why is H2O a covalent bond?

Answer 1

Any molecular bonding between the same elements is automatically covalent.

Answer 2

Yes, O2 is a covalent bond.

8 valence (outer-shell) electrons is a stable configuration, which is what every atom is trying to achieve.

There are only 6 valence electrons in one single oxygen atom, which means it is looking for another two valence electrons.

Since both oxygen atoms don't want to lose any valence electrons but want to gain two valence electrons, this means that they must each share two of their own with the other atom. Hence both atoms then have eight valence electrons. But because of their sharing electrons, they are stuck together because neither wants to lose their own two valence electrons. This is a covalent bond.

Answer 3

H2O forms a covalent bond because it consists of nonmetal atoms (oxygen and hydrogen). Covalent bonds involve the sharing of electrons between atoms to achieve a stable electron configuration. In the case of H2O, the oxygen shares electrons with the hydrogen atoms to form a stable molecule.

Answer 4

H2O is formed by covalent bonds because of the sharing of electrons between H and O. The H atom shares its electron with the O atoms. It does not donate that electron, it shares it.

Answer 5

yes
