2. Magnesium as atom:
Name: Magnesium Symbol: Mg  Atomic Number: 12  Atomic Mass: 24.305
Number of Protons/Electrons: 12  Number of Neutrons: 12  Classification: Alkaline Earth  Crystal Structure: Hexagona

3. Physical properties: Color: silvery- White metal Phase: solid
Crystalline structure: hexagonal
Ductility: It can be beaten into extremely thin sheets
Melleability: Capable of being shaped or bent
Luster: Exhibits a shine or glow
Hardness: Relatively soft

4. Chemical properties: Chemical Formula: Mg
Compounds: Oxide, hydroxide, chloride, carbonate and sulfate. Also Epsom salts (magnesium sulfate heptahydrate) and Milk of Magnesia (magnesium hydroxide)
Flammability: Burns in air with a bright white light
Reactivity:Upon heating, magnesium reacts with halogens to yield halides

5. Bonding: When Magnesium bonds with chlorine they make ionic bond.
Because: Ionic bonds are when atoms gain or lose electrons to become charged species (ions) that share an electrostatic interaction called an ionic bond.  Magnesium forms a positive ion (cation) with a 2+ charge and chlorine forms a negative ion (anion) with a 1- charge.  So two chlorine anions form an ionic bond with one magnesium cation for form MgCl2, a neutral chemical compound.  Metals and non-metals often form ionic bonds because of the difference in their electronegativity values. 

6. Mixture Mixture: Magnesium OIl: WHAT IS MAGNESIUM OIL?
First, I should clarify: magnesium oil is not an oil. It’s simply called magnesium “oil” because of the oily feel of magnesium chloride suspended in water. (Please note that this is not the same magnesium found in Epsom salt. Epsom salt is magnesium sulfate. This is magnesium chloride and is better suited for transdermal absorption.)
You’ll usually apply magnesium oil to your skin with a spray bottle, then rub it in and let your skin absorb it over the next half hour or so.

7. solution: magnesium citrate:
Clearing the bowels before tests or for treating constipation.
Magnesium citrate solution is a laxative. It works by attracting and retaining water in the intestine, which allows the bowel to evacuate.
