Is NCI3 and MgF2 a ionic compound?
NCl3 is not ionic but MgF2 is ionic
What is the overall charge of neon element?
Neon's overall charge is negative.
Is the MgF3 compond likely to occur?
No. Magnesium forms an ion with a 2+ charge while fluorine forms an ion with a 1- charge, so the resulting compound is MgF2. MgF3 would require magnesium to have a 3+ charge, which would be unstable.
How many GRAMS of magnesium fluoride are present in 4.78 moles of this compound?
The formula unit for magnesium fluoride is MgF2. From the periodic table, add the atomic weight of 1 magnesium atom and 2 fluorine atoms to get to get 62.3018. This means that 1 mole of MgF2 is 62.3018g of MgF2. Now, to find out the mass of 4.78 mol MgF2 X the g/mol so that you will cancel the moles, and keep the grams. 4.78 mol MgF2 X 62.3018g MgF2/1mol MgF2 = 297g MgF2 *The answer 297 is in keeping with significant figures. When you multiply or divide, the answer can have no more than the fewest significant figures in the calculation, which was 4.78, and which has only three significant figures.
What Substance Has An Overall Charge Of 1-?
An example is the hydroxyl ion: (OH)-.
Which has a higher melting point LiF or MgF2?
MgF2 is higher that LiF do to the greater bond strength in MgF2. This greater strength is indicated by the charge of Mg (+3) which is higher than the +2 charge of Li. Also the MgF2 is larger in mass.
What is the formula for magnesium and fluorine?

What is the overall charge of neon element?
Neon's overall charge is negative.
What is the overall charge of helium atom?
The overall charge on He is 0. It is a noble element.
Is the MgF3 compond likely to occur?
No. Magnesium forms an ion with a 2+ charge while fluorine forms an ion with a 1- charge, so the resulting compound is MgF2. MgF3 would require magnesium to have a 3+ charge, which would be unstable.
Which solution would elevate the boiling point of water the most MgF2 glucose KNO3 KBr?
MgF2
