What are the seven energy levels and tell the maximum number of electrons that can fit in each.
The seven energy levels, also known as electron shells or principal quantum numbers, are labeled as n = 1, 2, 3, 4, 5, 6, and 7. Each energy level corresponds to a specific distance from the atom's nucleus.
To determine the maximum number of electrons that can fit in each energy level, you can use the formula 2n^2, where n represents the energy level. Here's how you calculate it for each energy level:
For n = 1, substituting n into the formula:
Maximum electrons = 2(1)^2 = 2 electrons
For n = 2:
Maximum electrons = 2(2)^2 = 8 electrons
For n = 3:
Maximum electrons = 2(3)^2 = 18 electrons
For n = 4:
Maximum electrons = 2(4)^2 = 32 electrons
For n = 5:
Maximum electrons = 2(5)^2 = 50 electrons
For n = 6:
Maximum electrons = 2(6)^2 = 72 electrons
For n = 7:
Maximum electrons = 2(7)^2 = 98 electrons
Therefore, the maximum number of electrons that can fit in each energy level are as follows:
Energy Level 1 can hold 2 electrons.
Energy Level 2 can hold 8 electrons.
Energy Level 3 can hold 18 electrons.
Energy Level 4 can hold 32 electrons.
Energy Level 5 can hold 50 electrons.
Energy Level 6 can hold 72 electrons.
Energy Level 7 can hold 98 electrons.
