Respuesta :
Yes, atomic number is the number of protons and number of neutrons in the nucleus of an atom. The atomic number of the isotopes is same but their atomic masses are different.
Answer:
No
Explanation:
- Isotopes are atoms of same elements that have same number of proton (atomic number) but different number of neutron.
Example= 3 common isotopes of carbon are carbon12, carbon13 and
carbon14. They all have 6 protons and 6 electrons. But carbon12 has 6
neutrons, carbon13 has 7 neutrons and carbon14 has 8 neutrons.
- Ions are formed by gaining or losing electrons. The proton number is same.
Example= copper(i) ions and copper(ii) ions
both have 29 protons and 35 neurons but copper(i) ions
have 28 electrons and copper(ii) ions have 27 electrons.
