SSC MTS EXAM

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: -Metalloids generally form covalent bonds with non-metals. But sometimes, they form ionic compounds with other elements. SiO₂, silicon dioxide, is a covalent compound.

Detailed explanation-3: -Metalloids and non-metals not only form covalent bonds by sharing, but can form ionic bonds either by losing or gaining electrons. Note: However, transition metals tend to form coordinate covalent bonds due to relatively smaller sizes. The compounds formed by transition metals have significant covalent nature.

Detailed explanation-4: -Metallic bonding is the main type of chemical bond that forms between metal atoms. Metallic bonds are seen in pure metals and alloys and some metalloids.
