Question
How many electrons can fit in the second or third orbit?
- 2
- 8
- 4
- 16
Hint:
The general formula for number of electrons in a shell is 2n2.
The correct answer is: 8
- Each shell can contain only a fixed number of electrons
- The general formula for number of electrons in a shell is 2n2.
- The maximum amount of electrons that can fit in the second orbit of a Bohr-Diagram is 2(2)2 is 8 and for third shell is is 2(3)2 is 18.

How many shells are present in potassium?
The region surrounding a nucleus, known as an electron shell, is where electrons are typically located.
¶1s, 2s, 2p, 3s, 3d, 4p, 5s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, and 8s are the numbers in order. Although it is difficult to remember, there is a simple approach. Move from top to bottom, top right end to the bottom left of each line, in the order of the lines.
¶The lowest accessible shell nearest to the nucleus must be occupied by electrons.
¶The most electrons that can fit into each shell are:
¶There were two in the first shell, eight in the next, and eight in the last.
The twenty-first element, calcium, has two more electrons in the fourth shell.
