An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 - 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. If a neutral atom has 1 proton, it must have 1 electron. If a neutral atom has 2 protons, it must have 2 electrons. If a neutral atom has 10 protons, it must have 10 electrons. You get the idea.

You get the idea. In order to be neutral, an atom must have the same number of electrons and protons. - Protons = 40 Number of Electrons = Number of Protons - Number of Protons 40 - Electrons = 40 Number of Neutrons = Mass # - Protons - Mass # = 91 - Protons = 40 - Neutrons = 91 – 40 51 All matter, including mineral crystals, is made up of atoms, and all atoms are made up of three main particles: protons, neutrons, and electrons. As summarized in Table 2.1, protons are positively charged, neutrons are uncharged and electrons are negatively charged. The negative charge of one electron balances the positive charge of one proton.

0. If an atom has 24 protons and 24 electrons, what is the atomic number of this Des isotopes sont des atomes qui possèdent le même nombre de protons mais un nombre différent de neutrons. On connait 22 isotopes au sodium, leur nombre   6 Dec 2017 The atomic number, which is the number of protons, is 11. The number of protons is equal to the number of electrons. So sodium has 11 protons  Constitution d'un ion Na +. Noyau : Na. 11. 23.
