That is ionic bonding as well.
MgF2 isn't a covalent bond; it is an ionic bond. Magnesium is a metal and Fluorine is a nonmetal, so there is a complete transfer of electrons.
MgF2 and NaCl are ionic. NH3 and H2O contain polar covalent bonds. N2 contains non polar covalent bond.
MgF2 Magnesium, an alkaline earth metal of 2+ ionic charge and two fluorine, a nonmetal, atoms of 1- charge each form a ionic bond
MgF2 has a molecular weight of 24+19*2 = 62g. Thus, 31 grams of MgF2 represent .5mol. There are 6.022*10^23 particles per mole. Since MgF2 has three atoms in it, we can find the number of atoms by the following: (.5 mol)(6.022*10^23 particles/mol)(3 atoms in MgF2) = ... Enjoy your free high school chemistry answer!
1 Magnesium and 2 Fluoride
Yes it will form ionic bond (as in NaF or MgF2) or covalent bond as in F2 or ClF3)

1 Magnesium and 2 Fluoride
Fluorine gains an electron. Fluorine is very reactive and will form bonds.
CH4, covalent.
inoic because its a metal and a non metal bond
Br2 is a single covalent bond, where electrons are shared. MgF2 is an ionic bond because magnesium is a metal and bromine is a non-metal.
KClO3 ===========potassium chlorate The potassium, K +, is ionically bonded to the chlorate, a polyatomic ion, CLO3 -, but the chlorine and oxygen atoms are covalently bonded together.
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.
