No, the charge either pulls the electron cloud closer (cation) or pushes it away (anion).
The positive ion lost an electron.
The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.
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.
the ion has a greater number of electrons
no. atomic number will be same as the number of protons will not change for an ion and its neutral atom, but the number of electrons will vary.
When an atom of phosphorus gains three electrons to become a phosphide ion (P3-), it will have a larger radius compared to the neutral phosphorus atom. This is because the additional electrons will occupy outer electron shells, leading to increased electron-electron repulsion and the expansion of the ionic radius.
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
The positive ion lost an electron.
The positive ion has donated an electron to another atom making the other atom a negative ion and much larger in radius. The positive ion is now much smaller in radius.
The chlorine atom becomes an ion with a larger radius when it forms an ionic bond with sodium. This is because it gains an electron and becomes a negatively charged ion, causing the electron cloud to expand.
The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.
The nuclear charge is the same for both species, but the eight valence electrons in the sulfide ion experience a greater amount of electron-electron repulsion than do the six valence electrons in the neutral sulfur atom. This extra repulsion in the sulfide ion increases the average distance between the valence electrons, so the electron cloud around the sulfide ion has the greater radius.
If the number of protons and neutrons are the same, its an atom, if not its an ion
This occurs because a potassium atom has one more electron than a potassium ion in the ground state; the extra electron increases the size of the atom due to increased electron-electron repulsion, leading to a larger atomic radius than the potassium 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.
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.
A chloride ion is larger than a chlorine atom because it has gained an electron, leading to increased electron-electron repulsion and a larger ionic radius compared to the atomic radius of a chlorine atom.
