The ATOM decreases in size when it loses an electron and increases when electrons are added.
Any modification occur.
It shrinks loosing an electron.
It grows smaller in size.
It becomes a positive ion and atomic radius decreases in size, its divalent ion is more stable though.
The atom would stay the same size because it would still have the same amount of energy levels. The mass of the atom would be slightly less though.No, an atom shrinks when loosing an electron.There are less electrons ('-'charges) left that are attracted by the same number of protons ('+'charges) in nucleus, so the atraction per electron is stronger.
Just making sure, first off, that you realize electrons are not in the nucleus. They float in the empty space around the nucleus, of an atom. But if your asking what happens to the atom once it loses an electron, the atom then has a positive charge, and becomes a positive ion. The atomic size[of the atom alone] becomes smaller due to the greater pull the protons are able to have on the electrons.
they decreased in size but did not decrease in number
mass i think

Think of the sun as the nucleus and the oort cloud (past pluto) as where the electron orbitals start. The size (volume) of the nucleus is tiny compared to the size (volume) of the atom (defined by the extent of the electron cloud).
A cation is an element that loses electrons in order to achieve a pseudo-noble gas electron configuration:Hence, when a cation loses electrons it has an uneven number of (p+) and (e-). The protons then pull harder on the electrons or (e-) because there is more positive charged subatomic particles than there are negatively charged subatomic particles. The remaining electrons are closer to the nucleus making the cation smaller in size than the original atom.
It is impossible to know exactly where an electron is. Thus, the size of an electron cloud can be given only in terms of probability. Even then, the size of the electron cloud depends on how many electrons an atom possesses.
