WebOxygen is a chemical element with atomic number 8 which means there are 8 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. The ionic radius is not a fixed property of a given ion, but varies with coordination number, spin stateand other parameters. Nevertheless, ionic radius values are sufficiently transferableto allow periodic trendsto be recognized. As with other types of atomic radius, ionic radii increase on descending a group.
