one metalloid and one metallic element

Detailed explanation-1: -In general, covalent bonds form between nonmetals, ionic bonds form between metals and nonmetals, and metallic bonds form between metals.
Detailed explanation-2: -Answer and Explanation: As most non-metals have fully filled their outer shell with electrons, they tend to share their electrons rather than giving them up when bondin with other non-metals.
Detailed explanation-3: -Covalent bonding occurs between two non-metallic atoms characterized by the sharing of electron pairs between the atoms and other covalent bonds with electronegativity difference is greater than 2.0 (<2.0).
Detailed explanation-4: -Covalent bonds occur between identical atoms or between different atoms whose difference in electronegativity is insufficient to allow transfer of electrons to form ions.
