Covalent compounds are prevalent in nature and are the primary structure of most organisms. Based on the periodic table, which pair of elements would most likely form a covalent bond?

boron (B) and carbon (C)
aluminum (Al) and silicon (Si)
carbon (C) and oxygen (O)
magnesium (Mg) and sulfur (S)

Respuesta :

Based on the periodic table and due to their nonmetallic nature, carbon (C) and oxygen (O) form covalent bonds.

What is a covalent bond?

A covalent bond is a type of chemical bond in which elements share electrons. It is formed between nonmetals.

Based on the periodic table, which pair of elements would most likely form a covalent bond?

  • boron (B) and carbon (C). B is a metalloid and C a nonmetal, so they don't form covalent bonds.
  • aluminum (Al) and silicon (Si). Al is a metal and Si a metalloid, so they don't form covalent bonds.
  • carbon (C) and oxygen (O). Both C and O are nonmetals, so they do form covalent bonds.
  • magnesium (Mg) and sulfur (S). Mg is a metal and S a nonmetal, so they don't form covalent bonds.

Based on the periodic table and due to their nonmetallic nature, carbon (C) and oxygen (O) form covalent bonds.
