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:<br /><br />Ca, K, Cl, Si<br /><br />Explanation:<br /><br />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.<br /><br />In this case, the elements are:<br /><br />Ca (Calcium) - Group 2, Period 4<br />K (Potassium) - Group 1, Period 4<br />Cl (Chlorine) - Group 17, Period 3<br />Si (Silicon) - Group 14, Period 3<br /><br />The order of increasing atomic radius is:<br /><br />Ca > K > Cl > Si<br /><br />This 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.<br /><br />Therefore, the correct order for increasing atomic radius is Ca, K, Cl, Si.
