Mark as a brilliant please

Explanation:

Covalent bonds are chemical bonds in which two or more elements join together by sharing electrons, rather than transferring electrons, as is the case with ionic bonds. These bonds tend to occur with nonmetal elements of the periodic table. Water is a familiar substance comprised of hydrogen and oxygen linked by covalent bonds. These elements are considered to be covalent. Other elements that can form covalent bonds include nitrogen, carbon and fluorine.
