Heavy Metals Toxicity and the Environment

Heavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water. Their multiple industrial, domestic, agricultural, medical and technological appliions have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environment.

Interstitial Compounds | Physical & Chemical Properties

Transition metals react with elements such as hydrogen, carbon, nitrogen, boron etc. to form interstitial compounds. As vacant spaces of the transition metals are filled up by small atoms, these compounds are hard and rigid. The chemical properties of the parent transition metals are not altered during the formation of interstitial compounds.

Calcium, Chemical Element - structure, reaction, water

Chemical properties Calcium is a moderately active element. It reacts readily with oxygen to form calcium oxide (CaO): Calcium reacts with the halogens— fluorine, chlorine, bromine, iodine, and astatine, The halogens are the elements that make up Group 17 (VIIA) of the periodic table. Calcium also reacts readily with cold water, most acids, and most nonmetals, such as sulfur and phosphorus.
