Chemical series transition metals
Group, Period, Block 3 (IIIB), 5, 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 4472 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, __
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 Silvery white
Atomic Properties
Atomic weightIn reference to a certain isotope of a chemical element, atomic weight (more accurately relative atomic mass though also called simply atomic mass is the mass of one atom of the isotope expressed in units atomic mass unit amu) such that the Carbon-12 isot 88.90585 amuThe atomic mass unit amu , unified atomic mass unit u , or dalton Da , is a small unit of mass used to express atomic masses and molecular masses. It is defined to be 1/12 of the mass of one atom of Carbon-12. Accordingly, :1 u 1/N gram 1/(1000 N) kg (whe
Atomic radiusAtomic radius is the distance from the atomic nucleus to the outmost stable electron orbital in a atom that is at equilibrium and is measured in picometers or Angstroms. Atomic radii are called covalent radii (a reference to the types of bonds formed) whe (calc.) 180 (212) pm
