These are: Chemical elements in the second period Group 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 #Name 3 Li 4 Be 5 B 6 C 7 N 8 O 9 F , pThe p-block of the periodic table of elements consists of the last six groups. In the elemental form of the p-block elements, the highest energy electron occupies a p- orbital. The p-block contains all of the nonmetals and semimetals, as well as some of t
DensityFor other meanings of density, see density (disambiguation Density (symbol: rho Greek: rho) is a measure of mass per unit of volume. The higher an object's density, the higher its mass per volume. The average density of an object equals its total mass div, Hardness 0.8999 kg/m3Kilogram per cubic metre is the SI measure of density and is represented as kg/m³, where kg stands for kilogram and m³ stands for cubic metre. The density of water is about 1000 kg/m³, since a cubic metre of water weighs about a tonne. kg/m³" is sometimes (273 K), NA
AppearanceFor alternative meanings, see color (disambiguation). visual arts. Color (or colour is a sensation which (in humans) derives from the ability of the fine structure of the eye to distinguish three differently filtered analyses of a view. The perception of colorless
