Lithium has 3 protons, 4 neutrons, and 3 electrons.
Lithium protons
- Protons = atomic number
From the periodic table, find the atomic number of lithium.
The atomic number of lithium is 3. Hence, lithium has a total of 3 protons.
Lithium neutrons
- Neutrons = atomic mass – atomic number
The atomic mass of lithium is 6.941, so we’ll take the roundup value as 7. And the atomic number of lithium is 3.
Subtract the atomic number (3) from the atomic mass (7). Hence, lithium has a total of 7 – 3 = 4 neutrons.
Lithium electrons
- Electrons = atomic number
The atomic number of lithium is 3. Hence, lithium has a total of 3 electrons.
