Explicação
The charge of an atom is determined by the number of electrons it has. A neutral atom has an equal number of protons and electrons, so its charge is zero. When an atom loses or gains electrons, it becomes an ion and its charge changes. a. When an atom loses 2 electrons, it has 2 more protons than electrons, so it becomes a +2 ion.b. When an atom gains 1 electron, it has 1 more electron than proton, so it becomes a -1 ion.c. When an atom gains 4 electrons, it has 4 more electrons than protons, so it becomes a -4 ion.d. When an atom loses 5 electrons, it has 5 more protons than electrons, so it becomes a +5 ion.
