Question

An illustration shows the periodic table of elements.

Which of the following elements are most likely to form an ionic bond?

Answer 1

Elements that are most likely to form an ionic bond are those that are on opposite sides of the periodic table and have a large difference in electronegativity. These elements are typically a metal and a nonmetal. Examples of elements that are most likely to form an ionic bond include sodium (Na) and chlorine (Cl), magnesium (Mg) and oxygen (O), and potassium (K) and fluorine (F).
