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 are the ionic radii of positive ions smaller than their corresponding atomic radii?
Positive ions have lost electrons, resulting in fewer electron-electron repulsions within the electron cloud, causing it to shrink. This leads to a smaller ionic radius compared to the corresponding neutral atom.
A lithium atom that has lost an electron it comes near a Chlorine atom that has gained an electron what happens?
They form an ionic compound
Compare the size of the radius of a negative ion to its neutral atom?
The size of the Radius of a positve ion is smaller than a neutral atom because the postive ion has lost electrons, which means the outer most shell might be lost as well making the positve ion smaller and the nuetral atom remains the same
Is The Ca plus 2 ion larger than the Ca atom?
Mg2+ is larger Now, as for the logic behind this problem...The first thing to do is recognize that Ca2+ (Calcium) has lost 2 of its electrons, therefore its valence electron structure is the same as Ar's (Argon). Ar is in the same row as Mg. The trend for atomic radii is increasing to the left and down. Atomic radius increases to the left because the atoms to the right have more particles in the nucleus than their counterparts to the left; thus, the electrons are drawn closer to the nucleus, and the atomic radius is diminished.
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 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.

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.
