Question

What are two compounds scandium forms with other elements? Are these compounds ionic, covalent, or metallic? What are the common uses of these compounds?

Answer 1

Scandium(III) fluoride, ScF3 , and Scandium(III) iodide, ScI3

Step-by-step explanation:

Although, Scandium is a soft metal with a silvery appearance, and develops a slightly yellowish when oxidized by air. It reacts with this elements all belonging to halogen family to form componds:

1. 2Sc(s) + 3F2(g) → 2ScF3(s)

Reacts with fluorine to form scandium(III) fluoride

2. 2Sc(s) + 3F2(g) → 2ScF3(s)

Reacts with iodine to form scandium(III) iodide

Compounds formed with Scandium are metallic as Scandium is found in a group in the periodic table known as the transition metals.
