According to me the atomic size of an atom increases or decreses with the change in the number of shells. As atomic size is defined as the distance between the nucleus and valence shell of an atom. So, the addition of an electron does not effect the atomic size. As we can see in the Periodic Table that while moving along a group the number of electrons increases along with increase in no. of shells, while the atomic size tends to be increase with addition of shells and neglecting the addition of electrons. Same is the case while moving along a period. Atomic size decreases while the attraction between increased nuleus charge increases . Thus the size of the atom decreases.

Why does francium have the biggest atomic size?
Francium is located on the bottom left side of the periodic table of elements. Meaning it has the largest number of electron shells and lowest electron negativity. Thus having the biggest atomic size.
What is the size order for these scientific particles Proton Neutron Atom Electron Nucleus?
IIRC Atoms (contains Protons/Neutrons and electrons) Nucleus contains Protons and Nuetrons Proton atomic size 1 Nuetron atomic size 1 electron atomic size 1/1836 i.e the proton is 1836 bigger than the electron
Why does F- has larger size than F?
Fluorine ion (F-) has a larger size than a neutral fluorine atom (F) because the additional electron in the F- ion increases the electron-electron repulsion, causing the electron cloud to expand. This results in a larger effective atomic radius for the fluorine ion compared to the neutral fluorine atom.
Why is the atomic size considered to have no definite boundary?
Atomic size is defined as the distance between the nucleus and the outermost electron in an atom. Since electrons occupy regions of space called orbitals, which have fuzzy boundaries, it is difficult to pinpoint an exact boundary of an atom. Additionally, the electron cloud distribution is not uniform, making the atomic size less precise.
What change takes place as you move down in group 17 of periodic table in electron gain enthalpy?
on moving down the group the atomic size as well as nuclear charge inreases.But the effect of increase in atomic size is much more pronounced than that of nuclear charge and thus the additional electrons feels less attraction consequently electron gain enthalpy becomes less negative on going down the group
Why the atomic size of argon is more than chlorine?
The atomic size of an element is primarily determined by the number of electron shells and the effective nuclear charge experienced by the outermost electrons. In the case of argon and chlorine, argon has an additional electron shell compared to chlorine, resulting in a larger atomic size. This additional electron shell in argon leads to greater electron-electron repulsions that push the outer electrons farther away from the nucleus, increasing the atomic size.
What has a larger atomic radius sodium or potassium?
Potassium has a larger atomic radius than sodium. This is because as you move down a group in the periodic table, atomic size generally increases due to additional electron shells being added, leading to increased electron-electron repulsion and a larger atomic radius.
The addition of electron shells results in?
The addition of electron shells results in more shielding of electrons from the nucleus.
What effect does an additional proton have on atomic size?
An additional proton, in the same period (row) makes the radius smaller and the nucleus bigger. It also changes the element.
What is the Atomic size of oxygen?
The atomic size of oxygen is approximately 60 picometers (pm). The atomic size refers to the distance from the nucleus to the outermost electron shell in an atom.

How does bromines atomic radius compared chlorine?
Bromine's atomic radii is larger than that of chlorine.

What property increases going down a group in periodic table?
Atomic size increases going down a group in the periodic table. This is because additional energy levels are being filled with electrons, leading to an increase in distance between the nucleus and the outermost electron shell.
