Aluminium
Al: 13
2.8.3
So three energy levels
7: so far, chemists have only named 7 energy levels existing in all atoms. I think you meant to ask, "How many electron energy levels are occupied in an aluminum atom?" The answer is 3, as aluminum's electron-configuration is 1s22s22p63s23p1.
Aluminium
Al: 13
2.8.3
So three energy levels
aluminum has 13 electrons
so its electron configuration would be 1s22s22p63s23p1
there are 3 energy levels
An aluminum atom has 3 energy levels and can be found in period 3. Aluminum's atomic number is 13 and its symbol is Al.
3 energy levels
There are three of then.
3
Three (3) electrons in this energy level.
The formula to determine the number of electrons in an energy level is 2n2, where n is the number of the energy level. For the fifth energy level, n=5. So the total number of electrons possible in the fifth energy level is 2(52) = 50.
Each aluminum isotope has 13 electrons. In accordance with the Aufbau Principle those electrons will fill: 1s2, 2s2, 2p6, 3s2, 3p1. The shortcut notation is: [Ne] 3s2, 3p1.
2n2 where n is the energy level
2, 8, 18, 1 electrons in each energy level with a total of 4 energy levels.
Three (3) electrons in this energy level.
n = 1: 2 electrons n = 2: 8 electrons n = 3: 3 electrons
Third energy level

You can determine the number of electrons in the outer level by the goup numbers. Like aluminum (atomic number 13) will have three in the outer level. There will be two in the first inner level. in the second level there will be eight. and in the last three.
yes.they have the maximum number of electrons in their outer energy level?
The formula to determine the number of electrons in an energy level is 2n2, where n is the number of the energy level. For the fifth energy level, n=5. So the total number of electrons possible in the fifth energy level is 2(52) = 50.
the period number tells which is the highest energy level occupied by the electrons
It depends on what elements are involved. Iron has two electrons in its outer shell, Lead has four. While in a metal, the outer electrons flow freely over the surface of the solid, there is no net loss or gain of electrons, the atoms do not become ionized, and are considered to still have their original number of electrons.
Each aluminum isotope has 13 electrons. In accordance with the Aufbau Principle those electrons will fill: 1s2, 2s2, 2p6, 3s2, 3p1. The shortcut notation is: [Ne] 3s2, 3p1.
