The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

The protons in a nucleus are approximately 2 ✕ 10^−15 m apart. consider the case where the protons are a distance d = 1.93 ✕ 10^−15 m apart. calculate the magnitude of the electric force (in n) between two protons at this distance.

What structural formula represents 4 electrons shared between two atoms?
