- Atomic size increases with increase in period number. (as we move from above to below in a group) Atomic size decreases as we move from left to right in a period. Explanation: As period number increases, number of shells increase, so atomic size increases.

Apr 25, 2012 · As you move from left to right across a period, the number of protons in the nucleus increases. The electrons are thus attracted to the nucleus more strongly, and the atomic radius is smaller (this attraction is much stronger than the relatively weak repulsion between electrons).

Oct 20, 2015 · Atomic radius decreases across a period because valence electrons are being added to the same energy level at the same time the nucleus is increasing in protons. The increase in nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus.
Sep 20, 2022 · How does the atomic radius of different elements change across a period? How does atomic radius change from top to bottom within a group? Explain why the atomic radius of hydrogen is so much smaller than the atomic radius of potassium.
Dec 10, 2023 · Moving from left to right across a period, atoms become smaller as the forces of attraction become stronger. This causes the electron to move closer to the nucleus, thus increasing the electron affinity from left to right across a period.
Through the period, the core electron shell shrinks, because the charge of the nucleus increases. The outer electrons have no influence on the core electrons: In an electrically charged sphere, there is no electric field in the inside.
Mar 15, 2018 · Key Questions. How does atomic size increase on periodic table? Answer: Atomic size increases with increase in period number. (as we move from above to below in a group ) Atomic size decreases as we move from left to right in a period . Explanation: As period number increases , number of shells increase , so atomic size increases .
Across a period, the atoms become smaller due to the reason discussed in the section on atomic radius. So, when an electron is added to the valence shell, it will experience higher electrostatic attraction.
