If an element has seven electrons in its outermost shell then it is likely to have the ----------- atomic size among all the elements in the same period.

Open in App

Solution

Atomic Radii in a period:
From left to right atomic size decreases, number of outer shell electrons increases.
When the nuclear charge increases, the nucleus hold valence electron more strongly.
Hence the element with 7 electrons in its valence shell will have smallest atomic radii.
Conclusion
If an element has seven electrons in its outermost shell then it is likely to have the smallest atomic size among all the elements in the same period.
