: Increases (Fluorine is the most electronegative element). Metallic Character : Decreases. 4. Chemical Bonding and Reactions

Atoms of different elements with the same mass number but different atomic numbers (e.g., Argon and Calcium Isotones: Atoms having the same number of neutrons (e.g., 614Csub 6 to the 14th power cap C 816Osub 8 to the 16th power cap O , both have 8 neutrons). 3. Periodic Classification of Elements chemistry notes ssc
