How the atomic radii changes across the period?

1.	How the atomic radii changes across the period?
Answer» Increase in Nuclear charge and decrease in atomic size.......both are inversely proportional The atomic radii decreases because when we move from left to right in a period the no. of electron increases and charge of proton also increase then the proton charge also attract the valence electron then that lead to the decrease in atomic radii.?????? because when we move left to right then size of atom decrease due increase in atomic nuclear charge and no. of electron on orbit
