Answer» SOLUTION :(a) ARGON - Ar has 18 electrons. (b) Isotopes of an element have the same ATOMIC numbers but different mass numbers. The chemical properties of an element depends UPON the valence electrons. Isotopes of an element have the same number of valence electrons in their outermost orbit. Therefore, isotopes of an element SHOW similar chemtcal propertles. |
