Atom- Magnesium Atomic number-12 Atomic weight- 24.3050

Atomic symbol- Mg

What atoms it combines with to form compounds- When combined with oxygen it makes magnesium oxide.hydroxide(o2), chloride (chlorine) , carbonate (carbon), and sulfate (Sulfer). Properties- ductile, silver-white, chemically active metal with a hexagonal close-packed crystalline structure. It is malleable when heated. When heated, magnesium powder or ribbon ignites and burns with an intense white light and releases large amounts of heat. electronic configuration- 2 · 8 · 2
