When carbon dioxide is formed, one carbon atom forms double covalent bonds with two oxygen atoms. Carbon dioxide is considered A) less stable than the individual atoms because it is a gas. B) less stable than the individual atoms because it can be decomposed readily. C) more stable than individual atoms as now the outer energy levels of all atoms are filled. Eliminate D) more stable than the individual atoms because together they form a more massive substance.

Respuesta :

The answer is c more stable than individual atoms as now the outer energy levels of all atoms are filled

Answer: The correct answer is Option C.

Explanation:

Covalent bonds are defined as the sharing of electrons between the atoms that are combining together to form a bond. The compound formed from these bonds are known as covalent compound.

The atoms share electrons in order to gain stability by completing their respective valence shell.

Carbon dioxide is formed by the sharing of electrons between carbon and oxygen elements.

Electronic configuration of carbon: [tex][He]2s^22p^2[/tex]

This atom requires 4 electrons in order to complete its valence shell

Electronic configuration of oxygen: [tex][He]2s^22p^4[/tex]

This atom requires 2 electrons in order to complete its valence shell.

Hence, 2 atoms of oxygen will form covalent bond with 1 atom of carbon to form carbon dioxide molecule. The molecule formed is a more stable than the individual atoms.

Therefore, the correct answer is option C.
