4.) My Electrons A radium mass has 88 electrons in 7 energy levels. 86 of a radium atom's electrons are on energy levels one through 6. The last 2 electrons are on the 7th level energy. The electrons on the highest, or outermost, energy level called valence electrons and lost during chemical reaction. When one is lost a radium ion with a charge of +2 is formed because the ion has 2 more protons then it has electrons.
5.) My Atom Not all radium atoms have a weight of 226 amu. Some weigh as little ass 222 amu, and others as much as 228 amu.All radium atoms have 88 protons or else they would have different elements, the difference in the weight is caused by a different number of neutrons.
6.) My Properties Is a silvery, lustrous, soft, intensely radioactive. It readily oxidizes on exposure to air, turning from almost pure white to black. It is luminescent, corrodes in water to form radium hydroxine. The heaviest member of the alkiline- earth group it is the most volatile.

8.) My Compounds Radium comes from halogens, oxygen, hydrogen and other compounds. For each compound, a formal oxidation number of radium is given but the usefulness of this number is limited p-block elements in particular.

hydrogen9.) My Story Was fomerly used in self- luminious paints for watches, nuclear panels, aircraft switches, clocks, and instrument dials. In the mid-1920s, a lawsuit was filed by 5 dying "Radium Girls" dial painters who had painted radium-based luminious paints on the dials of switches and clocks. Used in medicine to produce radon gas, cancer treatment. at the beginning of the 19th century radium was used as addictive in products like toothpaste, hair cream, and even food items.
