Finding the number of electrons in an atom
WebPut the atomic number of the noble gas under this symbol so that you know the number of electrons. Then, continue writing the electron configuration of a certain element until you reach the correct number of electrons. WebFeb 26, 2014 · By definition, atoms have no electrical charge. The positive charges of the protons must balance the negative charges of the electrons. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons as well as 36 protons. For any element: Number of Protons = Number of …
