Which of the following are the correct order for INCREASING atomic radius? Si, CI, K, Ca Cl, Si, Ca k Ca.K.CI . Si

The correct order for increasing atomic radius is:Ca, K, Cl, SiExplanation:Atomic radius generally increases as you move down a group in the periodic table, and decreases as you move across a period from left to right.In this case, the elements are:Ca (Calcium) - Group 2, Period 4K (Potassium) - Group 1, Period 4Cl (Chlorine) - Group 17, Period 3Si (Silicon) - Group 14, Period 3The order of increasing atomic radius is:Ca > K > Cl > SiThis is because as you move down a group, the number of electron shells increases, resulting in a larger atomic radius. As you move across a period, the number of protons in the nucleus increases, which pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.Therefore, the correct order for increasing atomic radius is Ca, K, Cl, Si.
