6. Electron Configuration 1s 2s2 2p6 3s2 Period element:3 Group element:2

7. 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

8. 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.

9. 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

10. 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.
