Astatine And Francium Research Paper

Limited resources
Astatine (85At) and Francium (87Fr) are both rare elements found in nature, and are highly radioactive. Astatine was produced by Dale R. Carson, K.R. MacKenzie and Emilio Segrè, by accelerating Bismuth ions in a device called “Cyclotron”, but also found in the waste uranium. Francium was discovered by Marguerite Catherine Perey, a French chemist in 1939, and it is found in its purest form in nature, but is really scarce in the Earth’s crust.
“Alpha decay (4x2) is a radioactive process in which a particle with two neutrons and two protons is ejected from the nucleus of a radioactive atom.” The mass number is decreased by four and the atomic number is decreased by two. “Beta decay (e-) occurs when, in a nucleus with too many protons or too many

Astatine in the early ages of earth has long since disintegrated radioactively, but other radioactive elements sometimes decay into Astatine after they go through alpha or beta particles.
During the process of alpha decay Francium does an abnormal step. While losing two protons the element must turn into Astatine but instead ninety-nine percent of the time to relieve the pressure in the nucleus it goes through beta decay and becomes Radium (88Ra). Then Radium goes through alpha decay that skips Astatine. Francium shuttles atoms away from Astatine, causing Astatine to remain rare.
Astatine is at the same time far more stronger than francium. “If you had a million atoms of the longest-lived type of astatine, half of them would disintegrate in four hundred minutes. A similar sample of francium would hang on for just twenty minutes.” Francium is fragile and creating a visible sample will be almost impossible. And if created it would be extremely radioactive and would create an explosion. No one will ever produce a visible sample of Astatine either. But Astatine could be used for acting as a radioisotope in
