Answer 2

Hey friend,
Here is the answer you were looking for:
Let's first know about isotope:
The same elements with same atomic number but different mass number is called isotopes. The difference in mass number comes due to change in number of neutron.

Now,
The atom of an element has one proton and one electron but no neutron is know as hydrogen atom. We will represent Hydrogen atom by the symbol H.
