The Elements of Metal. The types of metals on the Periodic Table can be further broken down by other properties, but these are the basic types of metals. Continue exploring the Periodic Table by checking out element examples from all the types of elements.

#### Demonstrations - Calcium + Water

Calcium + Water . Calcium is a silvery-white metal; it is relatively soft, but much harder than sodium metal.Calcium is a meer of the alkaline-earth metals (Group II on the periodic table); these metals react vigorously with water, although not as violently as the Group I metals such as sodium or potassium:. Ca(s) + 2H 2 O(l) ——> Ca(OH) 2 (aq) + H 2 (g)
