How many maximum electrons are there in energy level 1?

Answer 1

Bohr discovered that the number of electrons in an energy level is equal to 2n^2, where "n" is the energy level of the atom.

The first energy level is 2 (1)^2= 2 electrons

The second energy level is 2(2)^2= 8 electrons...etc.

Answer 2

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)

Answer 3

maximum of 2 electrons

Answer 4

Two ( 1s2)
