Question

Based on patterns in the periodic table, which element is the least malleable in its solid state/
phosphorus (P)
strontium (Sr)
antimony (Sb)
copper (Cu)

Answer 1

Malleability refers to the ability of a material to deform under compressive stress, often characterized by the material's ability to form a thin sheet. In the solid state, malleability is generally associated with metals.

Among the options provided:
- **Phosphorus (P)** is a nonmetal and is known to be brittle.
- **Strontium (Sr)** is an alkaline earth metal and has reasonable malleability.
- **Antimony (Sb)** is a metalloid and, while somewhat malleable, is also more brittle than metals.
- **Copper (Cu)** is a highly malleable metal.

Given this understanding, **phosphorus (P)** would be the least malleable in its solid state, as it is a nonmetal and does not exhibit malleability like metals do.
