Radium is Element #88

1. My name in three different languages is Radium, Radium, and Radium. I got my name when my discoverer Marie Curie noticed my incredibly high level of radioactivity, a word that Marie Curie also created.
2.

3. My nucleus found in the most common isotope has 88 protons and 138 neutrons. My naturally occurring   isotopes are 223Ra (Half-Life:11.435 d), 224Ra (Half-Life:3.66 d), 225Ra (Half-Life:14.9 d), 226Ra (Half-Life:1599 y), 227Ra (Half-Life:42 m), and 228Ra (Half-Life:5.76 y).


4.I have 88 electrons in a single neutral atom of radium. I have seven electron shells.


5. My atomic radius is 215 pm


6. My pure elemental properties are a white color and luminescent.


7.My abundance in the universe is 0 parts per billion.


8. I form the compounds Radium Bromide



Radium Chloride



Radium Oxide

9. I was discovered by Marie Curie during 1898 while in pitchblende, a uranium rich ore, from the Czech Republic. I was discovered when Marie removed uranium from the pitchblende, which was found to be still radioactive after the uranium removed.

10. I am used for creating self-luminous paints, lightbulbs, helping cure and cause cancer.

11. I gave several glow in the dark paint factory workers diseases, which caused them to sue their employers.
