Potassium ions are colorless when pure, but acquire a pink tinge when exposed to air due to oxidation of the surface layer of metal atoms. Atomic Mass Number Does it conserve in a nuclear reaction? In aerospace, scandium-aluminum alloys are used to make lighter and stronger materials for aircrafts and spacecrafts. The raw material is treated twice with hydrogen fluoride. Nilson was able to isolate it from an ore found in scandinavia called euxenite; thus the name scandium was given to this element as it originated from that region. Also, the valency, valence electrons, and ionic properties of the elements are determined by the electron configuration. And to arrange the electrons, you must know the number of electrons in that element. Atoms that have the same number of protons but different mass numbers are called isotopes of each other. In the periodic table, potassium is one of the alkali metals. Since then, scientists have continued researching this elements properties and have made great strides in understanding how it can be utilized in various industries.
