Question: are alkali metals solids liquids or gases?
Answer: The alkali metals are solids at room temperature (except for hydrogen), but have fairly low melting points: lithium melts at 181ºC, sodium at 98ºC, potassium at 63ºC, rubidium at 39ºC, and cesium at 28ºC. They are also relatively soft metals: sodium and potassium can be cut with a butter knife.
