When an atom loses an electron, it typically becomes a positively charged ion (cation). This loss of an electron results in a reduction of electron-electron repulsion in the electron cloud, which allows the remaining electrons to be drawn closer to the nucleus. As a consequence, the atomic radius decreases. Thus, the atomic radius of an atom decreases when it loses an electron.
What else can I help you with?
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
What atom has higher atomic radius Na or Na plus?
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
Why the radius of an atom larger than the radius a positive ion formed from it?
The positive ion lost an electron.
What happens to the valence electron in an alkali metal when it combines with a halogen gas?
This electron is lost.
What happens when an atom that has lost an electron comes in contact with an atom that gained an electron?
They form an ionic compound.
What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
What happens to an atomic radius when an electrons is lost?

What atom has higher atomic radius Na or Na plus?
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
How does ionic radius differ from atomic radius?
Ionic radius is the size of an ion after it has gained or lost electrons, leading to a change in the electron configuration and thus its size. Atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outermost electron shell. Ionic radius is affected by the change in electron configuration, while atomic radius is more related to the position of the outer electrons in the neutral atom.
Why the radius of an atom larger than the radius a positive ion formed from it?
The positive ion lost an electron.
What is larger radius a sodium ion or chloride ion?
A chloride ion has a larger radius than a sodium ion, because the chloride has an additional complete valence shell of electrons compared to a sodium ion, but a sodium atom has lost the only electron in this valence shell that the sodium atom ever included to form a sodium ion.
What happens to the valence electron in an alkali metal when it combines with a halogen gas?
This electron is lost.
What happens when an atom that has lost an electron in contact with an atom that has gain an electron?
They form an ionic compound.
What happens when an atom that has lost an electron in contact with an atom that has gained an electron?
They form an ionic compound.
What happens when an atoms that has lost an electron comes in contact with an atom that has gained an electron?
They form an ionic compound.
What happens when an Atom that has lost in electron comes in contact with an Atom that has gained an electron?
They form an ionic compound.
What happens when an atom that has lost an electron comes in contact with an atom that gained an electron?
They form an ionic compound.
