Question

A water molecule (H20) is an example of a covalent bond because

Answer 1

Answer:

Covalent bond is the mutual sharing of electrons.The hydrogen and oxygen atoms that combine to form water molecules are bound together by covalent bonds. That's why water molecule H2O is an example of a covalent bond.

Answer 2

Answer:

Water molecule is an example of a covalent bond beacuse of the difference in electronegativity.

Explanation:

The water molecule is consists of two hydrogen atoms and one oxygen atom.

Electronegativity is defined as the ability of an atom to attract electrons in a chemical bond.

• If the difference in electronegativity of two atoms is greater than 1.8 they will make an ionic bond
• The polar covalent bond is formed if the difference is between 0.4 and 1.8.
• If it is less than 0.4 then a nonpolar covalent bond is formed.

The electronegativity difference between oxygen(3.44) and Hydrogen(2.2) is 1.24. So, it is an example of a polar covalent bond.
