Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.
A covalent bond is a chemical bond formed when two atoms share electrons. An ionic bond is the attraction between oppositely charged ions.
Which bond is the strongest single double or triple?
Experiments have shown that double bonds are stronger than single bonds, and triple bonds are stronger than double bonds. Therefore, it would take more energy to break the triple bond in N2 compared to the double bond in O2.
Can an atom be both a molecule?
Molecule is the general term used to describe any atoms that are connected by chemical bonds. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds.
This statement is false. Covalent bonds are formed when two atoms share two pairs of electrons. In this case, atoms covalently bind with each other in order to attain maximum stability. By covalent bonding, atoms fill up their outer electron shell.
