Calcium | Article about calcium by The Free Dictionary
Calcium reacts vigorously with hot water and with acids, giving off H 2 (this does not occur with concentrated HNO 3). Calcium reacts with flourine at lower temperatures and with chlorine and bromine above 400 C, yielding CaF 2, CaCl 2, and CaBr 2, respectively.
Noble gas - Wikipedia
The noble gas atoms, like atoms in most groups, increase steadily in atomic radius from one period to the next due to the increasing nuer of electrons. The size of the atom is related to several properties. For example, the ionization potential decreases with an increasing radius because the valence electrons in the larger noble gases are farther away from the nucleus and are therefore not

calcium | Definition, Properties, & Compounds | Britannica
The metal reacts slowly with oxygen, water vapour, and nitrogen of the air to form a yellow coating of the oxide, hydroxide, and nitride. It burns in air or pure oxygen to form the oxide and reacts rapidly with warm water (and more slowly with cold water) to produce hydrogen gas and calcium hydroxide.
