Isotopes have variable numbers of electrons. select the best answer from the choices provided t f

             False: Isotopes have variable number of Neutrons.

                        Isotopes are defined as those atoms of same element which have same number of protons but different number of neutrons hence, isotopes have different number of neutrons and mass number respectively.

Example:

Hydrogen have three Isotopes;

                          i) Protium-1 having 0 neutrons

                          ii) Deuterium-2 having 1 neutron

                          iii) Tritium-3 having 2 neutrons

While, when the number of electrons for a particular atom varies it results in the formation of ions of that atom.

Example:

Hydrogen when looses one electron it converts into H⁺

Nitrogen when gains three electrons it converts into N⁻³

Chlorine when gains one electrons it converts into Cl⁻

Magnesium when looses two electrons it converts into Mg⁺⁺
