The table below displays information about the first 36 elements in the periodic table.
The unit for atomic radius is a picometer (pm).
Ionization energy is a measure of the energy required to remove an electron from an atom of the element, forming an ion. Ionization energy is reported in kilojoules per mole of the element.
Electronegativity is the relative ability of an element’s atoms to attract electrons in a chemical bond. The values for electronegativity are given in Paulings, a unit named after American scientist Linus Pauling (1901-1994). Electronegativity values range from 0.70 to 3.98

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
