The difference in electronegativity between two atoms largely determines the type of chemical bond formed. Atoms with similar electronegativities will share electrons and form a covalent bond. In contrast, when the difference in electronegativity is large, electrons will be permanently transferred from one atom to another, forming an ionic bond. Using the figures below, determine the type of chemical bond (% ionic and % covalent) in the following element pairs (Hint: (1) The periodic table lists the electronegativities for all...
