why in the periodic table as we go left to right the atomic radius decrease?

Expert Answer:

As we move from left to right in the periodic table, the number of shells remains constant and the nuclear charge that is atomic number increases in the same period. As a result, the attractive force of the nucleus on the outermost electrons becomes more and more and hence the atomic size decreases.
