Each energy level can hold different number of electrons. The first energy level holds 2, second holds 8, and third holds 8. Because the first two energy levels of sodium can only hold 10 electrons, the sodium has a third energy level to hold the 11th electron.

The electron arrangement for sodium is 2-8-1. This means that sodium has 2 electrons in the first energy level, 8 electrons in the second energy level, and 1 electron in the third energy level. Sodium has 11 electrons in total.
Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
There's only one. Because of this it is very easy for sodium to lose that one electron so that it can have a full electron shell like that of neon. Sodium's first shell has two electrons, and it's second shell has 8 electrons.
Yes, sodium (Na) and chlorine (Cl) both have the same number of electron energy levels. In sodium, the first level has two, the second level has eight and the third level has one. In chlorine, the first level has two, the second level has eight and the third level has seven. They both have three electron energy levels.
A neutral sodium atom has 11 electrons. In its outer energy level, it has 1 electron. Sodium's electron configuration is 2-8-1.

According to the octet rule, sodium will lose its one electron to achieve a full outer energy level, making it stable. This forms a positively charged sodium ion with a stable electron configuration.

Sodium has one electron in its outermost principal energy level, also known as the valence shell.
There is one valence electron in a neutral sodium atom. Sodium has an electron configuration of 2-8-1, indicating it has one electron in its outermost energy level.
The Valence electron
In the ground state, a sodium atom has 1 electron in the 3rd energy level, in the 3s orbital. See the link below to see/print a periodic table that gives electron configurations for the elements.
When a sodium atom is heated and gives off a line spectrum, the outermost electron absorbs energy and gets excited to a higher energy level. As the electron returns to its original energy level, it releases this energy in the form of light, creating the characteristic line spectrum of sodium.
