site.iugaza.edu.psElements are divided between metals and nonmetals several elements with properties of both metals and nonmetals are called metalloids. Metals are elements that are generally solid, shiny in appearance, electrically conducting, and malleable (ةنويل) —that is, they can be pounded into flat sheets without disintegrating.
Effect of Heavy Metals on Plants: An Overview
www.ijaiem.orgHeavy metals were significant environmental pollutants; their toxicity is a problem of increasing significance for ecological, evolutionary, nutritional and environmental reasons [1]. They are group of metals and metalloids with atomic density greater than 4 g/cm3, or 5 times or more, greater than water [2] including copper (Cu),

THE p -BLOCK ELEMENTS
ncert.nic.inIt is interesting to note that the non-metals and metalloids exist only in the p-block of the periodic table. The non-metallic character of elements decreases down the group. In fact the heaviest element in each p-block group is the most metallic in nature. This change from non-metallic to metallic character brings diversity
