Calcium is reactive and, for a metal, soft (with difficulty, it can be cut with a knife). In contact with air, calcium develops a mixed oxide and nitride coating, which protects it from further corrosion. Calcium reacts easily with water and acids and the metal burns
Physical/Chemical Properties of Copper | Chemdemos
Use this demo to contrast the physical and chemical properties of matter. Chemical properties are based on the ability or inability of the substance to produce new substances. Copper''s malleability, color, luster, and thermal and electrical conductivity are contrasted with its ability to react with concentrated nitric acid and silver nitrate.
3) The nature of the oxide of alkaline earth metal in the period is basic, because metals form basic oxides. Like for example Calcium forms CaO which is basic in nature. 4) The no. of electrons in the penultimate shell of the element with valency -1, if we take chlorine which have valency -1 then it will have 8 electrons in penultimate shell.
