The element you described—highly conductive, highly reactive, soft, and lustrous—most likely belongs to the **alkali metals** group. Alkali metals (such as lithium, sodium, and potassium) exhibit these properties.

Mercury differs from other metals in that **it is not solid under normal conditions**; it is a liquid at room temperature.

Based on patterns in the periodic table, the element that is the least malleable in its solid state is **phosphorus (P)**. Phosphorus is a nonmetal, and nonmetals generally exhibit brittleness rather than malleability, unlike metals such as copper (Cu) and strontium (Sr). Antimony (Sb) is a metalloid and also less malleable than typical metals, but phosphorus is the least malleable among the options provided.

The correct statement that describes the properties of lanthanoids and actinoids is: **They are malleable and lustrous, and they tend to conduct both electricity and thermal energy.**

Both lanthanoids and actinoids typically exhibit metallic properties, including malleability, luster, and good conductivity of electricity and thermal energy.
