Chapter 6: Q6.12 CYL (page 323)

Give an example of an atom whose size is smaller than fluorine.

Short Answer

Expert verified

Helium is an example of an atom whose size is smaller than fluorine.

Step by step solution

01

Step 1:Atomic size along the period from left to right

As the number of protons increases in the elements from left to right in the same period, the electrons will enter the same valence shell, due to this, the effective nuclear charge increases. This leads to a decrease in the size of the elements from left to right in the periodic table.

02

Atom whose size is smaller than fluorine

The given atom fluorine belongs to the 17 th group in the periodic table. Fluorine is a second-period element. Only group that is left after this is group 18 and the size of group 18 element that is in the first period and is smaller than fluorine is helium.

There is another atom that is smaller than F-atom is Ne-atom.
