The number of electrons per orbit in an atom is determined by the energy level of the orbit. Each orbit can hold a maximum number of electrons, with the first orbit holding up to 2 electrons, the second holding up to 8 electrons, the third holding up to 18 electrons, and so on.
The maximum number of electrons that can be held in the third orbit of an atom is 18. This is based on the formula 2n^2, where n is the principal quantum number of the orbit. For the third orbit (n=3), the maximum number of electrons is 2 x 3^2 = 18.
About 14 or less sometimes it changes just kidding about 14 bye thi was Nyahrules
The largest Bohr orbit of the uranium atom can hold up to 92 electrons, as uranium has 92 protons. Each orbit in an atom can hold a maximum number of electrons given by the formula 2n^2, where n is the principal quantum number of the orbit.
Sodium has 1 electon in it's outer orbit, 8 in the second and 2 in the first.
Sodium has 8 electrons in the n=2 orbit. This is because the second energy level (n=2) can hold up to 8 electrons max. Sodium has 11 electrons in total, with 3 in the n=1 orbit and 8 in the n=2 orbit.
In a lead atom, the number of electrons in each orbit are as follows: 2 electrons in the first orbit (closest to the nucleus) 8 electrons in the second orbit 18 electrons in the third orbit 32 electrons in the fourth orbit

Magnesium has 3 electron orbits. The first orbit can hold up to 2 electrons, the second orbit can hold up to 8 electrons, and the third orbit can hold up to 8 electrons.

2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.

There are 2 electrons in the valence orbital of a Magnesium atom.
2 electrons orbit in the outer shell. If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
Two (2) electrons can be held in the first orbit.
