Detailed explanation-1: -According to the Pauling electronegativity scale, the electronegativity of Boron (B) is 2.04 and the electronegativity of F is 3.98. The ED between B and F is then 1.946. Since 1.94 is greater than 1.8, the bond is ionic.
Detailed explanation-2: -Since Be is metal and F is non-metal. Therefore, the bond between Be and F is an ionic bond because the difference between their electronegativity values is more than 1.9.
Detailed explanation-3: -One way to predict the type of bond that forms between two elements is to compare the electronegativities of the elements. In general, large differences in electronegativity result in ionic bonds, while smaller differences result in covalent bonds.
Detailed explanation-4: -As in this case we have Germanium (a metal) and fluorine (a non-metal), therefore they will form an ionic bond.
