<h2>Atoms whose atomic number are the same but whose mass numbers are different are called : Isotopes </h2>
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

Answer:
To break down the nucleus of an atom
Explanation:
Remember to change from one element to another, is necessary to add protons, neutrons and electrons,in most of the cases.
The take an electron from an atom you need certain energy, but they are in the outside part of the atom so is not as much energy as the one is necessary to take one neutron or proton from the inside part of an atom.
In this way, is a must to have a combination of pressure and heat to destabilize an atom and take some of this subatomic particles.
