What physical state is aluminium at room temperature?

A fine powder of aluminium metal reacts explosively on contact with liquid oxygen; under normal conditions, however, aluminium forms a thin oxide layer (~5 nm at room temperature) that protects the metal from further corrosion by oxygen, water, or dilute acid, a process termed passivation.

What is aluminum’s state of matter at room temperature?

At room temperature, the state of matter of aluminum is that of a solid. Aluminum is a metal that has an atomic weight of 26.98 grams per mole.

What state are most metals at room temperature?

Most metals are in the solid state at room temperature. The only metal that is in liquid state in the room temperature is Mercury, (Hg) 0.0.

What is the state of most non-metals at room temperature?

Physical State: Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (carbon). Non-Malleable and Ductile: Non-metals are very brittle, and cannot be rolled into wires or pounded into sheets.
