How many neutrons and protons in the isotopes #""^(25)Al#, #""^(95)Tc#, and #""^(120)Sn#?
Have you got a Periodic Table beside you?
And if the answer is no then amend this deficiency pdq. The Periodic Table classifies all the 100 or known elements on the basis of their atomic number
In the neutral particle,
Now we know the nuclear core contains protons, fundamental positively charged particles. They can also contain NEUTRONS, massive nuclear particles of ZERO electric charge, and this gives rise to the phenomenon of isotopes. For example, if a nucleus contains 1 proton, then by definition
As nuclei get larger, the element can support greater numbers of stable isotopes, and the quoted atomic mass on the Periodic Table is the WEIGHTED average of these isotopes.
So we have covered all of chemistry and physics. Finally, we get to your question. You gots
I will let you do the last isotope,
