Electrons are different from protons and neutrons in following ways:
1)Electrons have a negative charge
2) Electrons have negligible mass.
3) Electrons revolve around the nucleus in specific energy orbitals.
4) During chemical reactions it is the participation of electrons that gives different products.

Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
The mass number is the average atomic mass of all the isotopes that are found in nature.
The number of protons (and electrons in a neutral atom) is identical. The number of neutrons is different for each isotope.
Same number of protons, different number of neutrons
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
The atom has a nucleus in the middle made up of protons and neutrons. This nucleus is surrounded by a cloud of electrons which inhabit different energy levels at different distances form the nucleus. The electrons are negatively charged, the protons are positively charged and the neutrons are electrically neutral. An atom always has the same number of electrons as it does protons, so the atom itself is electrically neutral.
None -- all protons are protons, which are different from neutrons.
Protons are positively charged and neutrons are neutral.
Charge. Protons are positive, neutrons are neutral.
Electrons carry a negative charge, protons and neutrons do not.
Protons are positively charged Neutrons are negatively charged The number of protons is the atomic number Protons+Neutrons=Atomic weight
The individual protons and neutrons are basically indistinguishable; they don't have different names.
It could have 11 neutrons. This would be a different isotope
These particles are: protons, neutrons and electrons.
Atoms which have different number of protons and neutrons but have the same molecular weight are called Isobars.
Each chemical element has a different number of protons; the number of neutrons can be similar.
All isotopes of radium have the same number of protons; the number of neutrons is different.
