Hint: Both boron trifluoride, $B{F_3}$ and nitrogen trifluoride, $N{F_3}$are formed by covalent bonding that means the bonds in these compounds are formed by sharing of one or two pairs of valence, electrons. This attraction leads to the formation of an ionic compound. One mole of Calcium reacts with two moles of Bromine, therefore, the total number of valence electrons will be: Next, we put the least electronegative atom in the center. The atom losing electron(s) is usually a metal is and is called an electron donor while the atom gaining electrons (usually a nonmetal) is called an electron acceptor. Is CaBr2 Ionic Or Covalent?
