Cations vs Parent atoms

Postby Mallika Singh 1G » Sun Oct 27, 2019 10:14 pm

Could someone explain why cations are smaller than their parent atoms?

Cations are smaller than their parent atoms because there is less electron-electron repulsion but there is still the same number of protons so the electrons are closer to the nucleus.

Cations are smaller than their parent ions because cations lose electrons and when an atom loses electrons, the positively charged nucleus pulls the electrons more closely making it smaller.

Cations are smaller because they have less electrons which causes less repulsion making the protons pull closer to the nucleus.

Cations have less electrons and less electron-electron repulsion compared to the parent atom, so the electrons are pulled in more by the nucleus.
