Problem 27E
What are the possible values of the principal quantum number n ? What does the principal quantum number determine?
Solution Step 1 a)False. Cations are smaller in size than the corresponding parent atom.This is because cations are formed through the removal of outermost electron from the parent atom .Hence it has more of protons or the effective nuclear attraction will increase resulting in a smaller size cation. b)True Cations are smaller in size than the corresponding parent atom. c)False Size increases as we move down the group since a new shell is getting added with increase in - - value of the principal quantum number.Here,I comes below Clin the group and hence should be bigger in size than Cl -
