To identify the [[Atomic Nucleus|nucleus]] divide the [[Electrical Charge|charge]] by the [[Elementary Charge|elementary charge]] to find the number of [[proton]]s.
<math>Z = \frac{3.84\times10^{-18}}{1.60\times10^{-19}}</math>[[Coulomb|C]]
<math>Z = 24.0</math>
There are 24 [[proton]]s in the [[Atomic Nucleus|nucleus]].
