1. The problem statement, all variables and given/known data
state the number of protons electrons and neutrons of these:
Magnesium-25
Cu-65
2. Relevant equations
protons is the same as atomic numbber, same with electrons. NEUTrons is atomic number - atomic mass
3. The attempt at a solution
Magnesium-25 Cu-65
p- 12 p-29
e-12 e-29
n 25-12=13 n-65-29=36
am i right?
