Web2 jun. 2024 · If the atomic weight is 4.001, you can be confident the atom is helium, with 2 protons and 2 neutrons. An atomic weight closer to 5 is more troublesome. Is it lithium, with 3 protons and 2 neutrons? Is it beryllium with 4 protons and 1 neutron? If you're not told the element name or its atomic number, it's hard to know the correct answer. 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.
