✒ why does atomic radius changes as we move from left to right in a period ?

$\underline{\bf\red{ANSWER:-}}$

✒ The atomic radius of atoms generally decreases from left to right across a period because following reasons:-

• ➪ In a period, protons are added to the nucleus as electrons are being added to the same principal energy level. These electrons are gradually pulled closer to the nucleus because of its increased positive charge that's why atomic radius changes as we move from left to right in a period.
