Rank the following elements in order of their decreasing atomic diameter based on their effective nuclear charge:

A. Cs, Ba, Sr, Mg
B. Mg, Sr, Ba, Cs
C. Cs, Sr, Ba, Mg
D. Ba, Sr, Cs, Mg

Answer :

Final answer:

The atomic diameter or atomic radius of an element is determined by its effective nuclear charge. As we move down a group in the periodic table, the atomic radius generally increases. As we move across a period from left to right, the atomic radius generally decreases. Hence the correct answer is option B

Explanation:

The atomic diameter or atomic radius of an element is determined by its effective nuclear charge, which is the attraction between the positively charged protons in the nucleus and the negatively charged electrons in the outermost shell. As we move down a group in the periodic table, the atomic radius generally increases due to the addition of more energy levels. As we move across a period from left to right, the atomic radius generally decreases due to the increase in the effective nuclear charge.

Ranking the elements in decreasing atomic diameter based on their effective nuclear charge:

  1. Mg, Sr, Ba, Cs

Hence the correct answer is option B
