How many atomes of each element are in a formula unit of magnesium phosphate?
If you balance the charges of the magnesium ion and the phosphate polyatomic ion, you get a formula of Mg3(PO4)2. Now count 'em up: there are 3 magnesiums, 2 phosphrous, and 8 oxygens. (watch those parentheses!)
How many electrons are in magnesium's third energy level?
2 electrons are in magnesiums last energy level
Why is there only one oxygen ion in magnesium oxide?
Magnesium oxide has a chemical formula of MgO because magnesium (Mg) has a +2 charge and oxygen (O) has a -2 charge. When these ions combine, one magnesium ion and one oxygen ion are needed to balance out the charges and form a stable compound.
How does calcium atomic radius compare to magnesiums radius and potassiums radius?
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.

What is Magnesiums classification on the periodic table?
Magnesium is an Alkaline Earth element. It is a metal, and is very reactive.
What is magnesiums period number?
Magnesium's period number is 3. It is found in period 3 of the periodic table.
What is magnesiums state of matter at room temperature?
Magnesium "MG" is a solid at room temperature.
How many atomes of each element are in a formula unit of magnesium phosphate?
If you balance the charges of the magnesium ion and the phosphate polyatomic ion, you get a formula of Mg3(PO4)2. Now count 'em up: there are 3 magnesiums, 2 phosphrous, and 8 oxygens. (watch those parentheses!)
What is magnesiums point of fusion?
The melting point of Magnesium is about 650 deg C.
Why is it appropriate to group a polyatmonic ion in parenthesis in a chemical formula if more than one of that ion is present in the formula?
Assume you had a compound of magnesium phosphate, Mg3(PO4)2 As you can see, you need three magnesiums for every two polyatomic inonic phophates. Written like this would be very confusing; Mg3PO42, since polyatomics count their constituant atoms, the ones they are covalently bonded to. So, perenthesis are needed to maintain this distinction.
