With the help of the periodic table, we can easily see that the atomic number of sodium is 11. As its atomic number is 11, it has a total of 11 protons and for neutral sodium, the number of protons is always equal to the number of electrons i.e. 11 electrons in the nucleus.
WebSep 11, 2013 · The group is also known as a family or column. There are 18 groups in the periodic table. All the elements in a particular group have similar chemistry because the outer shells contain the same number of electrons.
