Question

In a reaction, chlorine accepts an electron to form Cl-. Which statement is true about the atomic size of the chlorine ion?
The atomic size of the chlorine ion is larger than the size of the chlorine atom.
The atomic size of the chlorine ion is smaller than the size of the chlorine atom.
The atomic size of the chlorine ion reduces to zero.
The atomic size of the chlorine ion is equal to the size of the chlorine atom.

Answer 1

In a chlorine atom it has 7 electrons, 7 protons and 7 neutrons.
When it accepts one electron then the constituents become 6 electrons , 7 protons and 7 neutrons.
Since there's an addition of one electron the atomic radius become big.
Therefore Cl^-1 ion has a larger radius than the chlorine atom.

Answer 2

So the answer is A
