Physical Properties of Barium

Barium is a silver-white metal, not so soft as lead, and of density 3.78. It melts at about 850° C., is volatile at 950° C., and boils at 1150° C. in vacuo. Its specific heat between - 185° and + 20° C. is 0.068. The maximum photoelectric effect is produced in the red and orange part of the spectrum. The ionic mobility of ½Ba is 55.

The following are the most intense lines in the spectrum measured in Angstrom units: -

Arc: Ultra-violet: 2304.3, 2335.4, 3071.7; Visible: 3891.9, 3910.0, 3935.9, 3993.6, 4130.8, 4283.3, 4350.6, 4402.8, 4554.2, 4579.8, 4726.6, 4900 1, 4934.2, 5424.8, 5519.4, 5535.7, 5777.9, 5800.3, 5826.5, 5853.9, 5971.9, 6019.7, 6063.3, 6111.0, 6141.9, 6497.1, 6595.6; Infra-red: 7060.2, 7229.2, 7280.6.

Spark: Ultra-violet: 2304.2, 2335.3, 2634.9, 2771.5, 3368.3, 3501.3; Visible: 3892.0, 3993.6, 4130.9, 4166.2, 4283.3, 4402.7, 4432.1, 4523.3, 4525.2, 4554.2, 4900.1, 4934.2, 5535.8, 5853.9, 6141.9, 6497.1, 6595.6, 6611.8.
