검증된 단계별 안내1
Understand that a chlorine atom becomes a chloride ion by gaining or losing subatomic particles.
Recall that protons determine the element's identity and are not gained or lost in ion formation; gaining a proton would change the element itself.
Recognize that neutrons affect isotopes but do not change the charge of the atom, so losing a neutron does not create an ion.
Know that electrons carry a negative charge, so gaining an electron increases the negative charge, forming a negative ion (anion).
Conclude that the process that changes a chlorine atom into a chloride ion is the gain of one electron.
