Why is the 11th electron of the sodium atom located in the third energy level?

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.

Do sodium and chlorine have the same number of electron energy levels?
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.
How many electrons are in the outermost energy level of a sodium atom?
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.
How many electrons are in the highest occupied energy level of the sodium?
Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
How many electrons does sodium have in its outer most shell?
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
Why is the ionization energy of a sodium atom greater than that of a potassium atom?
Caesium's single outer electron is much further from the nucleus than that of sodium, so caesium loses its valence electron much easily than sodium, therefore caseium is much more reactive than sodium.
Do sodium and chlorine have the same number of electron energy levels?
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.
How many electrons are in a neutral sodium's outer energy level?
One electron in 3s orbital of sodium
What is the name of the electron located in the outer most energy level?
The Valence electron

What has 12 neutrons and 1 electron in the 3rd level of the periodic table?
Sodium has 1 electron in the third energy level. 11Na23 isotope has 12 neutrons.
What is the number for electrons on hydrogen's first energy level?
Hydrogen's electron configuration is 1s1. It has only one electron. It is located in the first energy level.
How many electrons are in the highest occupied energy level in sodium?
Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
What principal energy level do the valence electrons occupy for Na?
The electron configuration of sodium is [Ne]3s1.
What energy level are the valence electrons located in lithium?
2nd energy level, the electron arrangement is 2,1 at ground state
How many electrons are in orbitals related to the third energy level of a sodium atom?
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.
What are the region around the nucleus where the electrons are located called?
electron cloud
How many electrons are in the highest occupied energy level of the sodium?
Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
