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.

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.
