Arrange the elements in each of the following in order of decreasing shielding effect:

(a) Li, Na, KOrder: K > Na > Li.The shielding effect increases as you move down the group because there are more electron shells, leading to more shielding. (b) Cl, Br, IOrder: I > Br > Cl.The shielding effect increases as you move down the group due to additional electron shells. (c) Cl, BrOrder: Br … Read more

Which atom has a higher shielding effect, Li or Na?

Sodium (Na) has a higher shielding effect than lithium (Li). This is because sodium has more electron shells (3 shells) compared to lithium (2 shells), and the inner electron shells shield the outermost electron from the pull of the nucleus more effectively, reducing the effective nuclear charge experienced by the outer electron.
