The full explanation of metal and nonmetal elements.

The melting point is the temperature at which a solid begins to convert to a liquid. The boiling point is the temperature at which a liquid begins to convert to gas.

Explanation of The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume).

Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, melting point, and boiling point. For the elements, color does not vary much from one element to the next.
