This is quite an important symbol in the list of hazard symbols and meanings because it shows that the substance does not burn itself but produce enough oxygen for other inflammable substances to burn. Salts are composed of related numbers of cations (positively charged ions) and anions (negatively charged ions) so that the product is electrically neutral (without a net charge). Many of these symbols were designated during the early years of radiochemistry, and several isotopes (namely those in the decay chains of actinium, radium, and thorium) bear placeholder names using the early naming system devised by Ernest Rutherford.[14]. In addition to the letters for the element itself, additional details may be added to the symbol as superscripts or subscripts a particular isotope, ionization, or oxidation state, or other atomic detail. The isotopic composition varies in terrestrial material such that a more precise atomic weight can not be given. Most chemical elements are represented symbolically by two letters, generally the first two in their name. hydro, water, and genes, forming) Hydrogen was prepared many years before it was recognized as a distinct substance by Cavendish in 1776.
