| 9, 6A period 6 element is one of the chemical elements in the sixth row (or period of the periodic table of the elements, including the Lanthanides. These are: Chemical elements in the sixth period Group 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 #Name 55 C, dThe d-block of the periodic table of elements consists of those periodic table groups that contain elements in which, in the atomic ground state, the highest-energy electron is in a d- orbital. The d-block elements are often also known as transition metal

| 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
| 22650 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, 6.5
