Chemistry for Kids: Elements - Calcium
Calcium is the third element in the second column of the periodic table. It is classified as an alkaline earth metal.Calcium atoms have 20 electrons and 20 protons. There are 2 valence electrons in the outer shell. Calcium is an important element for life on Earth and
HOCl will also react with HCl, one of the decomposition products. HOCl + HCl → H 2 O + Cl 2 (10) Hypochlorite bleaching solutions must not contain heavy metal ions, as these ions (like light or heat) promote the decomposition of HOCl, as shown in equation 11.
