Question

Atoms whose atomic number are the same but whose mass numbers are different are called: alpha particles ions beta particles isotopes

Answer 1

Atoms whose atomic number are the same but whose mass numbers are different are called : Isotopes

Explanation:

Isotopes

They are the   elements with same atomic number but different mass number .

for example : Protium , deuterium and tritium are isotopes of hydrogen .

                    : C-14 and C-12 are isotopes of oxygen .

                     : Cl-35.5 and Cl-37 are isotopes of chlorine

Alpha particles

They are helium nuclei with +2 unit charge and 4 a.m.u mass

They are represented as : He₂⁴.

Ions

The atom carrying charge is called as ion .

It can be of two types : Cation and anion

cation :atom with positive charge

Anion : atom with negative charge

Beta particles

They are actually particles with charge and mass of electron and is represented as :₀ e⁻¹
