Answer the following questions

Isotopes
The number of protons in a nucleus determines the identity of the element. For example, any
atom having 6 protons will be a "carbon" atom. If we were to add an extra proton to the nu-
cleus, we would have an entirely different element. For example,
C (6 protons) +1 proton
→ N (7 protons)
On the other; hand, if we add an extra NEUTRON to a nucleus we simply end up with the
same element, just a little heavier, since the charge on the nucleus would be unchanged.
ISOTOPES of a given element have the same ATOMIC NUMBER but a different
ATOMIC MASS.
In other words, isotopes have the same number of protons but a different number of neutrons.
An isotope is identified by its mass number, the sum of the protons and neutrons. The most
common isotope of Carbon has a mass number of 12 and can be written as Carbon-12, two other
isotopes are Carbon-13 and Carbon-14. Despite their different mass umbers, all three carbon isc
react the same way chemically.
