Question

Which of the following is generally FALSE? Group of answer choices Elements in the same group have the same valence electron configuration. Completely empty and completely full shells are very stable. Atomic radius of elements in a group decreases as you go from top to bottom. First ionization energy of elements in the same group decreases as you go from top to bottom. All of these statements are false.

Answer 1

Answer: Option (c) is the correct answer.

Explanation:

Generally, when we move from top to bottom in a group then there occur increase in the number of electrons due to which there will also occur increase in the number of shells.

As atomic size is the distance between the nucleus and valence shell of an atom. Hence, more is the number of shells present in an atom more will be its atomic radius.

Thus, we can conclude that the statement atomic radius of elements in a group decreases as you go from top to bottom, is generally FALSE.
