WebRadium is a chemical element with atomic number 88 which means there are 88 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. WebSep 22, 2016 · Radium is a naturally occurring radioactive element, number 88 on the periodic table. It emits particles from its nucleus as it decays into other, lighter elements, and is itself the byproduct of the decay of the heavier element uranium into lead.
