The protons and neutrons cluster together to form the nucleus, the central part of the atom, and the electrons orbit about the nucleus. Protons and electrons both carry an electrical charge(电荷). The charges they carry are opposite to each other; protons carry a positive electrical charge whi...
The nucleus is found at the center of the atom and contains subatomic particles that are called protons and neutrons. Protons carry a positive charge, whereas neutrons carry no charge. The protons and neutrons are held together in the nucleus by the nuclear strong force, which overcomes the rep...
