chemical element: Ca
( small chips )
Calcium Metal chips.
Calcium is a chemical element; atomic number 20. Calcium metal reacts with water evolving Hydrogen gas and producing an
alkaline Calcium Hydroxide solution. When ignited in air, Calcium metal burns
with a bright white light, forming Calcium Nitride.
In vacuum systems, small amounts of Calcium metal serves as a 'getter' for
residual gasses. Calcium forms a thin white oxide layer on its surface
that protects the metal from additional oxidation.
