Katisha Correll Element Research Project 5/28/2010 Period: 6 Name of element • Magnesium • Magnesium got its name from magnesia Element Symbol • Magnesium symbol is Mg • Mg atomic number is 12 • Mg atomic mass is 24.305 Mg boiling point • 1363k (1090c) boiling point • 923(650c) melting point • 293k: 1.738g/cm3density Mg number of protons • Mg is known to be an solid • Mg has 12 protons • 12 electrons • 2 valence electrons Electron Configuration • 1s 2s2 2p6 3s2 • Period element:3 • Group element:2 Abundance • Magnesium on earths crust is found as the seventh most abundance element • The ionic bond between ions results from the electrostatic attraction of opposite charges. • The color of magnesium can be determined as grayish or silver-white Abundance con. • Magnesium is the eighth most abundant element in the universe • The second most abundant compound in the earths crust • Ions usually make solid charges. Discovery of Magnesium • Magnesium was discovered by Joseph Black, in England,in1755. • Isolated by A.A.B. Bussy and Sir Humph key Davy in 1808. • Magnesium has 8 isotopes • The crystal structure of magnesium is hexagonal Discovery of Mg cont. • Mg comes from Thessaly, Greece. • Magnesium is present in as many as 60 minerals on the surface of the Earth. • This alloy is used for making beverage cans. Magnesium is used in electron components for it’s good electrical and mechanical properties and light weight. • It is used in manufacturing devices such as cell phones, cameras,computers, etc. Comparison facts • Similar elements are Calcium,Beryllium,Strontium, Barium and Radium. • http://www.web elements.com/index.html • http://www.chemicool.com/
