Mass Number: Total number of protons and electrons
Atomic Number: Total number of protons
Electrons = Protons
Ion: charged particle
NB: as long as the atom has not been chemically bonded, because the number of electrons will change.
Compound: atoms of two or more elements which have been chemically bonded together
Isotope: different atomic forms of the same element but with the same number of protons, but different numbers of neutrons.
- Between non-metals and metals.
- The non-metals gain electrons- negative charge (because there are more NEGATIVE electrons that the POSITIVE protons).
- The metals lose electron - positive charge (because…
