✔ 最佳答案
1. The number of protons in a helium nucleus is 2. Thus, a pair of helium nuclei will result in a nucleus with 4 protons, and it is beryllium.It is C.2. For the nucleus to have the greatest amount of electrical charge, the number of protons should be the highest.
So, the answer is D. Uranium has 92 protons in the nucleus.
