one Scientific experiments show that the charge of the nucleus and electron in the atom are two opposite charges. Physics stipulates that the charge of the nucleus is positive, and the charge of the nucleus and electron in the hydrogen atom is one charge each. The charge they carry is expressed by positive and negative numbers. I know about positive and negative numbers, but I don't know about nucleus, electron and charge

Nucleus in hydrogen atom: e + (one charge, the number "1" can be omitted)
Electron in hydrogen atom: e-
Note: the charge is indicated by the letter "e"
Positive charge: e+
Negative charge: e-
