WebJan 30, 2024 · The value of the ionization energy (2370 kJ mol -1) is much higher than hydrogen, because the nucleus now has 2 protons attracting the electrons instead of 1. Lithium is 1s 2 2s 1. Its outer electron is in the second energy level, much more distant from the … WebThe atomic number of lithium is 3. That is, the number of electrons in lithium is 3. Therefore, a lithium atom will have two electrons in the first shell and one in the 2nd shell. Therefore, the order of the number of electrons in each shell of the lithium (Li) atom is 2, 1. Electrons can be arranged correctly through orbits from elements 1 to 18.
