Electron theft at its finest! That's basically the entire plot of ionic bonding—chlorine, the desperate electron hoarder with 7 valence electrons, just needs one more to complete its outer shell and achieve noble gas stability. Meanwhile, sodium's sitting there with a single valence electron, practically begging to be mugged. The chemical equivalent of a back-alley deal where sodium gets stability by emptying its pockets and chlorine gets that sweet, sweet octet completion. Chemistry isn't about sharing—it's about knowing when to take what you want.
