Hi, so for Ionic Bonds atoms will give up an electron to another atom for that atom to form an octet. Is there a maximum amount of electrons one atom can give and are there any exceptions or rules that follow what atoms can form ionic bonds and which can not?
In the textbook with the Na+ example, a sodium ion will lose its 3s electron to form Na+. It does not lose more because the ionization energies of core electrons are too high. And nonmetals will rarely lose their electrons but would rather gain them to fill their valence shells.
Also, normally atoms will only lose as many electrons until they have the same electron configuration as a noble gas, or so that they fill their octet. Say an atom as 12 electrons with two valence electrons. It is unlikely to lose more than 2 valence electrons because once it does it is in a stable state with high electronegativity.
Typically atoms will either gain or lose an electron until it form a noble gas configuration. It depends on which is easier to do for the element. Metals will more likely lose electrons and nonmetals will gain electrons.
