State of matter of radium
WebRadon is produced during the breakdown of radium. It is obtained commercially by the following method. A compound of radium is placed under water. Gases given off by the radium compound are collected in a glass tube. Oxygen, nitrogen, water vapor, carbon dioxide, and other gases are removed from the gas in the tube. The gas that remains is … 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.
