As the elements in Period 2 of the Periodic Table are considered in succession from left to right, there is a decrease in atomic radius with increasing atomic number. This may best be explained by the fact that the

Anumber of protons increases, and the number of shells of electrons remains the same
Bnumber of protons increases, and the number of shells of electrons increases
Cnumber of protons decreases, and the number of shells of electrons remains the same
Dnumber of protons decreases, and the number of shells of electrons increases

The decrease in atomic radius with increasing atomic number is best explained by the fact that ; ( A )

  • The number of protons increases and the number of shells of electrons remains the same .

In the periodic table the atomic number of elements in period 2 will continue to increase as you move from left to right, because there is an increase in protons which causes an increase in positivity in the charge carried by each element  while the number of shells of the electrons remain constant therefore as we move from left to right the Elements will attract more negative charges to themselves.

As the atomic number increases there will be a corresponding decrease in the atomic radius of the elements.

Hence we can conclude that. The decrease in atomic radius with increasing atomic number is best explained by the fact that The number of protons increases and the number of shells of electrons remains the same.
