Sodium (Na) has only one electron in its outer electron shell, as shown in Figure 1. Once again, gaining one electron is more energy efficient than losing seven. As a result, it appears to obtain an electron, resulting in an ion with 17 protons, 17 neutrons, and 18 electrons, and a net negative charge (–1).
Answer:most of the positively charge particles should be bounce back at a range of angles as they collide with the atoms in the foil; only a few should pass straight through the foil
