Question

The circles, or orbits, for electrons are called energy levels. Each level can hold only a certain number of electrons. Add electrons to each level until you can add any more. How many electrons can each level hold?
IF YOU GIVE ME THE RIGHT ANSWER I WILL GIVE YOU BRAINIEST OR WHATEVER ITS CALLED!!!!!!!

Btw this subject is Science but I couldn’t find it so I just put chemistry.

Answer 1

Answer: n = 1 can hold a maximum of 2 electrons

n = 2 , maximum 8 electrons

n = 3, maximum 18 electrons

As per the principles of quantum mechanics, the number of electrons that can be added to a given energy level is deduced based on the three quantum numbers: n, l , m(l) and m(s)

'n' is the principal quantum number which defines the energy level. It can take on integer values: 0,1,2,3...

'l' is the angular momentum quantum number which defines the shape of the orbital that an electron occupies

l = 0,1,2...(n-1)

where: l = 0 corresponds to s-orbital

l = 1 corresponds to p-orbital

l = 2, corresponds to d-orbital

'm(l)' is the magnetic moment quantum number which defines the orientation of an orbital  in space.

m(l) = -l, 0, +l

'm(s)' is the spin quantum number which defines the orientation of an electron is an orbital m(s) = +1/2 or -1/2

An s, p or d-orbital can accommodate a maximum of 2, 6 and 10 electrons respectively For energy level with n= 1

l = 0, i.e. s-orbital or 1s.

Therefore, the maximum number of electrons for a 1s orbital would be 2 resulting in an electron configuration of 1s²

For energy level with n= 2

l = 0, 1 i.e. s and p-orbitals

The maximum number of electrons would be

Electron configuration: 2s²2p⁶

For energy level with n= 3

l = 0, 1, 2 i.e. s, p and d-orbitals

The maximum number of electrons would be

Electron configuration: 3s²3p⁶3d¹⁰
