Detailed explanation-1: -2 Non-Metals is the correct answer. Explanation: In general, metals and nonmetals conjoin to form ionic compounds, and nonmetals combine with other nonmetals to form covalent compounds (molecules). A covalent bond is formed between 2 non-metals.

Detailed explanation-2: -Covalent Bonding This type of bonding occurs between two atoms of the same element or of elements close to each other in the periodic table. This bonding occurs primarily between nonmetals; however, it can also be observed between nonmetals and metals.

Detailed explanation-3: -In general, covalent bonds form between nonmetals, ionic bonds form between metals and nonmetals, and metallic bonds form between metals.

Detailed explanation-4: -Covalent bonds form primarily between nonmetal elements, although these types of bonds can occur between metals and nonmetals.

Detailed explanation-5: -For example, beryllium and aluminium are both metals but they bond covalently with chlorine to form beryllium chloride and aluminium chloride respectively.
