Lithium atom atomic number
WebVandaag · Looking at the Lithium box that we drew above, we can say that the atomic mass of the Lithium atom is 6.938. After rounding it up to the nearest whole number we get 7. Also, as calculated above, the number of protons in the Lithium atom is 3. Now, finding the number of neutrons by applying the formula: Number of neutrons in the Lithium … WebThe atomic number represents the number of protons in an atom, so Lithium has 3 protons. The atomic mass is the number of protons and neutrons of an element. As seen on a periodic table, Lithium has an atomic mass of 7. We know the proton number is 3, so 7-3 = 4, is our number of neutrons. Finally, as an atom is neutral in charge, the protons ...
