Question Answer
Chlorine molecules (Cl₂) form single covalent bonds between chlorine atoms. Explain what the 'single covalent bond' means? Hint- Valence Electrons A pair of electrons is shared between the Cl atoms so that each Cl atom has 8 valence electrons. A single covalent bond is formed.
Oxygen molecules (O₂) form double covalent bonds between oxygen atoms. Explain how this bonding occurs? Two pairs of electrons are shared between the O atoms so that each O atom has 8 valence electrons.
