Sodium has 1 electron in the third energy level. 11Na23 isotope has 12 neutrons.
When reading the periodic table top to bottom, the number of electron energy levels increase. This is because each row in the periodic table corresponds to one electron energy level. The number of energy level corresponds to the period number of the element.
There are 11 protons and 12 neutrons. And that does not depend on the periodic table. Sodium had 11 protons and 12 neutrons long before the periodic table, or even human, beings existed!
hydrogen has no family on the periodic table.. its a loner
No. Atomic hydrogen has one proton and one electron.

Hydrogen contains 1 electron, 1 proton, and 0 neutrons. It is on the periodic table represented by the letter H.
Neutrons are not given directly on the periodic table. However the number of neutrons can be indirectly calculated. Mass number = Number of protons + number of neutrons
12 neutrons
A period on the periodic table is a row.This is the horizontal section of the periodic table.

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.

With the exception of hydrogen, all elements have an electron cloud, and a nucleus composed of protons and neutrons. Hydrogen has a single proton nucleus orbited by a single electron.

Periods on the periodic table are rows that categorize elements based on the number of electron shells they have. There are seven periods in total, each representing a different energy level. Elements in the same period have similar properties due to their electron configurations.
