Very soft and malleable, indium has a melting point higher than sodium and gallium, but lower than lithium and tin. Because it is more electronegative than most metals, phosphorus reacts with metals at elevated temperatures to form phosphides, in which it has an oxidation number of -3. The ordering of the electrons in the ground state of multielectron atoms, starts with the lowest energy state (ground state) and moves progressively from there up the energy scale until each of the atom’s electrons has been assigned a unique set of quantum numbers.

Fermium is a member of the actinide series. P–P or P–H bonds are also found in addition to P=O bonds and P–OH bonds in oxoacids of phosphorus where the oxidation state of phosphorus is less than +5. After brief exposure to high-purity oxygen or high-purity water vapor at room temperature, we observed phosphorus in the +1 and +2 oxidation states; longer exposures led to a large population of phosphorus in the +3 oxidation state. The oxidation number of a compound is 0. Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl. Naturally occurring potassium is composed of three isotopes, of which 40K is radioactive. The sum of the oxidation states within a compound or ion must equal the overall charge. Tellurium is chemically related to selenium and sulfur. Oxidation states are typically represented by integers which may be positive, zero, or negative.
