The elements B and F whether form ionic or covalent compound has to be ascertained. The empirical formula and name of the compound formed by elements B and F have to be given. Concept Introduction: Empirical formula of a compound represents the proportion of the elements in a compound irrespective of the numbers of atoms arranged in the molecule of the compound. Name of compound based on its empirical formula is empirical name of the compound. Ionic bond is the electrostatic force of attraction that binds ions of opposite charges into a stable molecule. Electronegativity difference between the atoms must be greater than 1.7 to form ionic bond between these atoms. Covalent bond refers to the bond formed between two atoms by mutual sharing of electrons – that each atom shares equal number of electrons between them and the charge distribution (electron) between the two atoms held by covalent bond is symmetrical. The difference in electronegativity between these two atoms is very less or the two atoms have same electronegativity. Electronegativity difference between the atoms must be nil or highly lower than 1.7 to form covalent bond between these atoms.
