Atomic number (the number of protons in the nucleus), not atomic mass number (the number of protons and neutrons), determines chemical behavior. 是原子序数(原子核中质子的数量)而不是原子的质量决定化学特性。 全句 We now know that atomic number (the number of protons in the nucleus), not...
The total number of protons and neutrons in the nucleus of an atom. For example, nitrogen has 7 protons and 7 neutrons in its nucleus, giving it a mass number of 14. The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014 by Houghton Mifflin Harcourt Publishin...
and has more electrons than protons. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. If an ion...
