Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust. It is the Pauli exclusion principle that requires the electrons in an atom to occupy different energy levels instead of them all condensing in the ground state. This fact has key implications for the building up of the periodic table of elements. Relative atomic massThe mass of an atom relative to that of carbon-12.

Very soft and malleable, indium has a melting point higher than sodium and gallium, but lower than lithium and tin.
Electronegativity
A measure of how difficult it is to deform a material. It is given by the ratio of the shear stress to the shear strain. A measure of the stiffness of a substance. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain. Specific heat capacity is the amount of energy needed to change the temperature of a kilogram of a substance by 1 K.
