Introduction to positive and negative numbers in grade one of junior high school 1. Scientific experiments show that the charge of the nucleus and the electron in the atom is opposite. The charge of the nucleus is positive. The nucleus and the electron in the hydrogen atom each have one charge. The charge is expressed by positive and negative numbers The answers on the fourth floor are more complete

Because the atom is not charged, the positive and negative charges should be offset, that is, 0. Because the nucleus and the electron in the hydrogen atom each have one charge, 1 + (- 1) = 0
therefore
Nuclear charge in hydrogen atom + 1
Electron charge in hydrogen atom: - 1
The term "charge number" is not correct. Charge is a number
