a company plans to make an electronic device. They need to use an element that has chemical behavior similar to that of Silicon (Si) and Lead (Pb). The element must have an atomic mass greater than that of Sulfur (S), but less than that of Cadmium (Cd). Use the periodic table to determine which element the company can use.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
