Answer:
20
Explanation:
yes, we can find the no of the neutron in the given atom as the mass number is the sum of the number of neutrons and protons in an atom.
no of proton = atomic number of atom = 20
no of neurons = mass number of atom - atomic number if atom or no of protons = 40 - 20 = 20 neutrons
(40.078 can be rounded off)

Answer:
No
Explanation:
This is because the numbers of neutrons may vary in respect to the number of protons. These variations form isotopes of the elements. For example, in a carbon atom where there are same numbers of protons and neutrons (6) it is called Carbon 12. But if there are two more neutrons there, it forms the isotope Carbon 14.
