An atomic number is typically written as a subscript before the chemical symbol of an element. For example, the atomic number of oxygen is written as 8O. It represents the number of protons in the nucleus of an atom.
The atomic number is typically not used together with the atomic symbol because the atomic symbol already implies the atomic number. The atomic symbol consists of one or two letters, with the first letter capitalized, and the second letter, if present, in lowercase. The atomic number is the number of protons in the nucleus of an atom and is unique to each element.
One way to write the isotope of bromine with 10 more neutrons than its atomic number is 81Br (atomic number 35 + 10 = 45 neutrons). Another way is to use the mass number notation and write it as bromine-81, where the mass number is the sum of protons and neutrons.
Li
Lithium's atomic number is 3. Thus, it has 3 protons in each atom, all of which have a +1 charge. To be electrically neutral then, lithium must also have 3 electrons per atom.
