Web17 dec. 2024 · K+ has a bigger effective nuclear charge than Cl−, which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have a larger atomic radius. WebCorrect option is C) Given ionic radii of K + and F − 1.34 Ao, Atomic radii of K and F respectively would be 1.96 Ao, 0.72 Ao. Because F is smaller in size than K. And when …
Web26 jun. 2024 · Therefore more the protons more is the force of attraction on electrons.Removing electrons does not change the atomic number. As we know that Ca=20 and K=19 therefore there cations also have same atomic number.Hence Ca+2 having more protons (no. of protons is same as atomic number) means more force which means a … Web23 jun. 2024 · Each proton carries a +1 charge; the more protons an atom or ion contains the stronger the attraction it poses on its electron cloud. A nucleus of strong positive charge pulls its electron cloud towards itself tightly such that the latter would have a small radius. The periodic table is arranged in the order of increasing proton number.
