Which of the following is the correct order of ionic radii?
- a)Na+ < Mg2+ < Al3+ < Si4+
- b)Al3+ < Si4+ < Na+ < Mg2+
- c)Si4+ < Al3+ > Mg2+ > Na+
- d)Na+ > Mg2+ > Al3+ > Si4+
Correct answer is option 'D'. Can you explain this answer?

Which of the following is the correct order of ionic radii?a)Na+ < ...
All ions shown have the same number of electrons i.e. 18. But the number of protons are different. Thus more the number of protons, more is the attractive force experienced by the electrons and consequently smaller is the ionic radius of the ion. Thus the order becomes as shown in option D. (14 protons of Si(4+) attract 18 electrons more effectively than 11 protons of Na(+)).

Which of the following is the correct order of ionic radii?a)Na+ < ...
Na+, Mg2+, Al3+ and Si4+ are isoelectronic cations with 10 electrons, but when we go from Na+ to Si4+, one unit nuclear charge increases. Thus, the ionic size of isoelectronic species is compared on the basis of their atomic number/number of electrons, i.e. Z/e ratio. Smaller the value of Z/e, larger the size of the species. For example,
