The first shell is just 1S, which can hold 2.
[The second shell is 2S, 2P which can hold 8 total (2+6)
[The third shell is 3S, 3P, 3D which can hold 18 total (2+6+10)
[The fourth shell is 4S, 4P, 4D, 4F which can hold 32 total (2+6+10+14)
The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
The 3rd energy level of an atom can hold a maximum of 18 electrons.
The first energy level of an atom can hold a maximum of 2 electrons.
In the 3rd energy level, there can be a maximum of 4 electrons.
The maximum number of electrons that can be held in an energy level is given by the 2n^2 rule, where n is the principal quantum number of the energy level. So, for example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
The 3rd energy level of an atom can hold a maximum of 18 electrons.
The first energy level of an atom can hold a maximum of 2 electrons.
The second energy level of atoms can hold a maximum of 8 electrons.
In the 3rd energy level, there can be a maximum of 4 electrons.
Maximum of 8 electrons in second energy level.
There could be a maximum of 8 electrons in the second energy level (n = 2)
The first energy level can take a maximum of two electrons.
The maximum number of electrons that can be held in an energy level is given by the 2n^2 rule, where n is the principal quantum number of the energy level. So, for example, the first energy level (n=1) can hold a maximum of 2 electrons, the second energy level (n=2) can hold a maximum of 8 electrons, and so on.
Iron has 26 electrons. The third energy level can hold a maximum of 18 electrons. Therefore, there are 18 electrons on the third energy level of iron.
In the second energy level of an atom, there can be a maximum of 8 electrons. Magnesium has 12 electrons in total, with 2 electrons in the first energy level and 8 electrons in the second energy level.
Maximum of 2n2, where n is the energy level.
