How do elements actually keep their shape and the same number of electrons as they bond and detach from other elements. Is it just the magnetic pull that keep them together? Once they lose or gain electrons how do they regain or get rid of them after?
In the case of NaCl Na becomes a cation (+) and Cl becomes an anion (-) Na+Cl- to form sodium chloride. With this the ionic bond it is now stable. The - charge indicates that the electron was added and a + charge means a electron was lost. If the charges aren't labeled then the bond isn't considered stable.
