Isotopes
These are the elements having same atomic number but different mass number. They have the same atomic number because the number of protons inside their nuclei remains the same. The difference in their mass number is due to the difference in their n..
Isotopes
Atoms of the same element having the same atomic number but different mass numbers are called isotopes. The nuclei of these atoms have same number of protons but different number of neutrons. All the properties of the isotopes..

Isotopes of Hydrogen
All isotopes of the same element have the same number of protons, but a variable number of neutrons. The isotopes of hydrogen have the following structures (Fig.9.1)...
