D. Reichenstein measured the electrode potential of phosphorus in soln. of potassium hydroxide, and sulphuric acid. R. Schenck found the potential difference of the hydrogen-phosphorus couple to be 0-168 volt at 13-6°, so that the phosphorus electrode is negative to that of hydrogen. W. Beetz studied the gas-cell with phosphorus vapour, and platinum with occluded hydrogen O. S. Duffendack and H. Huthsteiner, the low- voltage arc in phosphorus vapour. W. Busse measured the distribution of the sizes of the ions in phosphorus vapour and found that there is a continuous gradation from the largest to the smallest. 

A number of toxicologically important organic compounds have sulfur bound to phosphorus. The simplest of these are the phosphine sulfides, containing only carbon, hydrogen, phosphorus, and sulfur, as illustrated by the example below ... 

Living cells depend principally on a supply of carbon, oxygen, nitrogen, hydrogen, phosphorus, and sulfur. In addition their biochemistry...

The atomic number of an element indicates the number of protons in the nucleus of the atom. All atoms of the same element have the same number of protons in the nucleus. In the periodic table (inside this book s front cover) the atomic number for each element is given above the element s symbol. There is a different atomic number for each element, beginning with the atomic number 1 for hydrogen. Phosphorus, for example, has an atomic number of 15 thus, the nucleus of a phosphorus atom contains 15 protons.

When heated in nitrogen, P3N5 decomposes according to (4.177) in hydrogen, phosphorus and ammonia are obtained and in air, the final residue is polymeric (P205) . Triphosphorus pentanitride is decomposed on heating with concentrated nitric acid or by fusion with alkalies. If it is heated with certain metallic nitrides, it produces salt structures with continuous networks of P-N bonds (see below). 

Dalton later devoted much attention to the natural zero of temperature, or absolute privation of heat , which had occupied Crawford, and Lavoisier and Laplace (see p. 429). He gives nine methods of finding it the fusion of ice, mixing sulphuric acid and water, slaking lime, the action of nitric acid on lime, and the combustion of hydrogen, phosphorus, charcoal, oil, etc., and ether. The results varied from 4150 to 11,000° below 32 F., the mean being 6150 .
