This meant the metal would float on water --at least, it would do if it didn't explode as soon as it came into contact with the water. temperature, while others are liquids and others are solids. One of the common and, perhaps, most noticeable properties that most metal elements share is that they corrode when exposed to seawater or air. As you can see, Lithium, Beryllium, Sodium, Magnesium, Aluminum, Potassium, and Calcium are metals out of the first 20 elements. Elemental nonmetals mostly are in a gaseous state at room temperature, while others are solids. Potassium is in the fourth row in family IA on the periodic table. 1 Answer.
