🌟 Basic Info:
Symbol: Mg
Atomic Number: 12
Atomic Mass: 24.305 u
Group: 2 (Alkaline Earth Metals)
Period: 3
Block: s-block
🔥 Physical Properties:
Appearance: Shiny, silvery-white metal (when it's not oxidized)
Density: 1.738 g/cm³ (super lightweight — think diet metal)
Melting Point: 650 °C (that's hot, but not lava hot)
Boiling Point: 1,090 °C
Hardness: Relatively soft (like a marshmallow in metal terms)
⚡ Chemical Properties:
Highly reactive, especially with oxygen — leave it in air and boom, oxide coating!
Burns with a bright white flame — like a star with drama.
Reacts with water (very slowly in cold water, faster with steam).
Forms Mg²⁺ ions when it gives away its two valence electrons like a generous little donor.

In fireworks and flares for that Insta-worthy blinding white light
In construction alloys — it's lightweight but tough, like a ballerina with brass knuckles

Magnesium supplements — because your muscles and mood deserve it
Milk of magnesia — sassy name, serious digestive help
🧪 Fun Fact:
If magnesium catches fire, don't throw water on it. It'll just laugh and burn hotter — classic drama queen behavior.
