Question

As we move from left to right across a period, there is regular decrease in atomic radii of the representative elements. This is due to the reason that (A) the number of energy shells remains the same while nuclear charge decreases (B) the number of energy shells remains the same while nuclear charge increases (C) the nuclear charge remains the same while number of shells decrease (D) both number of shells and nuclear charge remain the same.

Q. As we move from left to right across a period, there is regular decrease in atomic radii of the representative elements. This is due to the reason that

the number of energy shells remains the same while nuclear charge decreases

the number of energy shells remains the same while nuclear charge increases

the nuclear charge remains the same while number of shells decrease

both number of shells and nuclear charge remain the same.
