In a atom the number of electrons are equal
WebAtoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. If it gains one or more electrons, it now carries a net negative charge, and is thus "anionic." WebSince an atom must have an overall neutral charge, the number of protons and electrons found within an atom of an element must be equal. Therefore, every atom of tungsten also contains 74 electrons. The mass number of an atom is calculated by adding together the number of protons and neutrons that are found within that atom, as shown below.
