50
For fermium: 30 electrons.
For fermium: 30 electrons.
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.
Maximum of 8 electrons
2!
The fifth electron shell, also known as the fifth energy level or n=5, can hold a maximum of 50 electrons. This is calculated using the formula 2n^2, where n is the principal quantum number.
In a barium atom, there are 2 electrons in the first energy level, 8 electrons in the second energy level, 18 electrons in the third energy level, 18 electrons in the fourth energy level, 8 electrons in the fifth energy level, and 2 electrons in the sixth energy level.
In oxygen, the third energy level can hold a maximum of 18 electrons. However, oxygen only has 8 electrons in total, so only 2 electrons are found in the third energy level.
2 are both found in the 1s orbital of an atom
The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
Calcium has 2 valence electrons. It is in group 2 of the periodic table, which means it has 2 electrons in its outermost energy level.
There are 7 outer orbital electrons in an atom of chlorine, as it has 7 electrons in its outermost energy level.
