Which of the following elements would you expect to have chemical properties similar to Fluorine (F)? A Argon (Ar), because they are both noble gasses.

B Beryllium, (Be) because they are in the same period.

C Chlorine (Cl), because they are found in the same group.

D Neon (Ne), because they have almost the same number of protons.

Covalent bonds generally form when the bonded elements have a difference in electronegativity less than 1.5. subtract the electronegativities for the following pairs of elements and predict whether they form a covalent bond. electronegativity difference of c and c: ionic covalent electronegativity difference of mg and cl: ionic covalent
