WebDec 10, 2024 · Graduation of atomic radius property in the periodic table In the horizontal period : The atomic radius decreases as we go from the left to the right across a period by increasing the atomic number from 1A to zero group . This is due to the gradual increase in the effective nuclear charge ( Z eff) which increases the nuclear attraction force on the … WebA higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. Down a group, the number of energy levels (n) increases, so there is a greater distance between the nucleus and the outermost orbital. This results in a larger atomic radius. 2. daffin\u0027s candies sharon pa https://mertonhouse.net
