Question

8. In the modern periodic table along the period moving from left to right the atomic radius
​

Answer 1

Answer:

In the Modern Periodic Table, the atomic radius increases while moving from right to left in a period. Atomic radius decreases from left to right within a period. ... One proton has a greater effect than one electron, thus, electrons are pulled towards the nucleus, which results in a smaller radius.

Answer 2

Answer:

Atomic size gradually decreases from left to right across a period of elements. This is because, within a period or family of elements, all electrons are added to the same shell. ... The valence electrons are held closer towards the nucleus of the atom. As a result, the atomic radius decreases.
