Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium oxide is more normally made by heating calcium carbonate. Calcium, immediately below magnesium in the periodic table is more reactive with air than magnesium.

Chlorine - Newikis
Chlorine is the second halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to fluorine, bromine, and iodine, and are largely intermediate between those of the first two.Chlorine has the electron configuration [Ne]3s 2 3p 5, with the seven electrons in the third and outermost shell acting as its valence electrons.
chlorine | Definition, Properties, & Facts | Britannica
Chlorine, chemical element of the halogen group that is a toxic, corrosive, greenish yellow gas, irritating to the eyes and respiratory system. Present-day salt deposits must have been formed by evaporation of prehistoric seas, the salts with the least solubility in water crystallizing first, followed by those with greater solubility. . Because potassium chloride is more soluble in water than

Chlorine - Production and use | Britannica
17/8/2020· Chlorine - Chlorine - Production and use: Rock salt deposits are usually mined; occasionally water is pumped down, and brine, containing about 25 percent sodium chloride, is brought to the surface. When the brine is evaporated, impurities separate first and can be removed. In warm climates salt is obtained by evaporation of shallow seawater by the Sun, producing bay salt. Chlorine is produced
Chlorine (Cl) - Structure, Properties, Uses, and FAQs
Chlorine is the second halogen in the periodic table, being a nonmetal in group 17. Hence, its properties are similar to fluorine, bromine, and iodine, and are generally intermediate among those of the first two. Chlorine has the electron configuration [Ne]3s23p5, with
Chlorine bleach is a solution of sodium hypochlorite and water. Chlorine gas is produced when sulfuric acid is mixed with chlorine bleach. This reaction is a function of the change in pH of the solution from alkaline to acidic coined with the strong oxidant properties
