WebDec 24, 2024 · The Lewis dot model shows the number of valence electrons present in the atom. Since the given metal has 2 dots, it indicates that the metal atom must have 2 electrons in its outermost shell. Therefore option 2 : It has two electrons in the innermost energy level, is wrong because it contains 2 electrons in the outermost energy level WebThis is called Lewis dot notation. The next element on the periodic table, helium, has an atomic number of 2, which means that it has two protons and two electrons. Since the neutral helium atom has two electrons, the Lewis dot notation for helium has two dots next to the He symbol.
