Who found that the atomic number was equal to the number of protons in the nucleus and to the number of electrons outside the nucleus in a neutral atom? Meyer Newlands O Moseley ooo Mendeleev Thomson
Which of these statements is true? The number of electrons outside the nucleus is the same as the number of neutrons in the nucleus. The mass number of an atom is the number of protons plus the number of neutrons. The atomic number of an atom is the number of valence electrons outside the nucleus. In an ion, the number of electrons must be equal to the number of protons.
