It's because as atomic radius increases, so do the number of electron shells. The full electron shells closer to the nucleus act like a barrier or shield that reduces the pulling force exerted by the Nucleus on the outer electron. Since the nucleus's pulling force is reduced, an electron on the outer shell can escape much more easily.

What happens to the atomic radius when an electron is gained?

The negative ionic radius is larger than the neutral atomic radius


Why does an increase in atomic radius lead to a lower ionization energy?

An increase in atomic radius leads to a lower ionization energy because the outermost electrons are farther away from the nucleus, which weakens the attraction between the electrons and the nucleus. This makes it easier to remove an electron, resulting in a lower ionization energy.


What is the Group trend Atomic radius?

The group trend for atomic radius is that it tends to increase down a group in the periodic table. This is because as you move down a group, the number of electron shells increases, leading to a larger atomic radius. Additionally, the effective nuclear charge decreases down a group, which also contributes to the increase in atomic radius.


What is the atomic radius of iodide ion?

The atomic radius of a iodide ion is approximately 206 picometers. It is larger than the atomic radius of a neutral iodine atom due to the addition of an extra electron, which increases the electron-electron repulsion and causes the electron cloud to expand.


What is the correlation of ionization energies to atomic radii for the elements?

There is an inverse relationship between ionization energy and atomic radius: as atomic radius increases, ionization energy decreases. This is because as the distance between the nucleus and valence electrons increases, the attraction between them weakens, making it easier to remove an electron.

How does electron shielding explain why it is easier to remove an electron from rubidium than from lithium?

In rubidium, having a larger atomic radius, the attraction force between the atomic nucleus and and the electron from outermost shell is lower.

What element has the larger atomic radius b or c?

Element b would have a larger atomic radius than element c as you move down a group on the periodic table, the atomic radius tends to increase. This is because each successive element has an additional electron shell, leading to an increase in size.


How does the atomic radius of argon compare to krypton?

The atomic radius of argon is smaller than the atomic radius of krypton. This is because as you move down a group on the periodic table, the atomic radius tends to increase due to the addition of extra electron shells. Argon is located above krypton in the periodic table, so it has a smaller atomic radius.


Why the atomic radius increase in column of periodic table?

The atomic radius increases down a column in the periodic table because as you move from top to bottom, each element has an additional energy level or shell of electrons. This increase in electron shells results in a larger average distance between the nucleus and the outermost electrons, leading to a larger atomic radius.


What trend in atomic radius do you see as you go down a group on the periodic?

The atomic radius of elements increases as you go down a group. This increase in radius as you go down a period is primarily caused by the increasing principal quantum number of the outer electron shells.


Si has a larger atomic radius than C?

Yes Atomic radius of carbon: 60 pm Atomic radius of silicon: 110 pm
