Answer:

ALL ISOTOPES OF AN ELEMENT HAVE THE SAME NUMBER OF;

1. PROTON

2. ATOMIC NUMBER

Explanation:

Isotopes are atoms with the same atomic number but different mass numbers. Isotopes of an element has the same number of proton which dictates the atomic number of the atoms. The difference in mass number is as a result of the difference in the number of neutrons. Isotopes of an atom have different physical properties but they exhibits the same chemical properties because neutrons have no influence on the chemical properties and the change or difference in neutrons will produce no effect on the chemical properties of the atoms. Neutrons only contributes to the mass of the atoms giving the isotopes of an atom different mass numbers. An example is chlorine with two isotopes, Cl -35 and Cl -37.

Properties                            Cl-35                                                    Cl-37

mass number                        35                                                        37

atomic number                      17                                                         17

number of protons                17                                                          17

number of electrons                17                                                       17

number of neutrons        35-17 = 18                                             37-17 = 20

abundance in nature             75%                                                    25%

From the given information;

  • all isotopes of an element do not have the same number of neutrons,
  • have the same number of protons
  • have the same atomic number
  • do not have the same mass number
  • have the same chemical properties.

An isotope is are two or more atomic element that contains the same equal number of protons in the nucleus of an atom but with a different number of neutrons.

They share the same similar chemical properties and they behave in the same manner in the chemical reaction but have different mass numbers due to the different number of neutrons.

The difference in their mass numbers influences the rate of their chemical reactions.

They also exhibit different stability. While some are stable, some are unstable, and they can be referred to as radioactive isotopes.

Therefore, we can conclude that:

  • all isotopes of an element do not have the same number of neutrons,
  • have the same number of protons
  • have the same atomic number
  • do not have the same mass number
  • have the same chemical properties.
