What element has 5 energy levels?

Answer 1

The Pauli exclusion principle states that no two electrons in the same system can exist simultaneously in the same state. The state of an electron is determined by three things:

Its energy level N

Its angular momentum L

and its spin S

The electron can only have a spin of +1/2 or -1/2, so there are only two states that an electron can be in for a given L and N.

The electron's angular momentum L depends on the state N that it is in. L must be an integer whose magnitude is less than N, so it can have (2N - 1) different states for a given N. (For example, if N = 2, L can equal -2, -1, 0, 1, 2).

The energy level N is also given as a (nonzero) positive integer (N can equal 1, 2, 3, 4, etc.). In an element's ground state, EVERY SINGLE electron state must be filled. So an element with five electrons in the fourth energy level N, energy levels 1, 2, and 3 must be filled, and energy level 4 must have five electrons in it.

The number of electrons in energy level 1 is the number of spin states time the number of angular momentum states for the level N, that is 2 spin states times (2N-1) angular momentum states = 2

For energy level N = 1, the number of electrons can be 2 * (2N-1) = 2

For energy level N = 2, 2 * (2N-1) = 6

For N = 3, 2 * (2N-1) = 10.

So the first three energy levels, when filled, contain 2 + 6 +10 = 18 electrons. The fourth energy level has 5 electrons according to the question, so there must be 18 + 5 = 23 electrons in total.

The element with 23 electrons, or an "atomic number" of 23 is Vanadium.

Answer 2

Oh, dude, that would be Vanadium with its atomic number 23. It's like the cool kid at the Periodic Table party with its 5 energy levels, just chilling and attracting electrons like it's no big deal. So yeah, Vanadium is the answer you're looking for.

Answer 3

The elements in column six, the Nitrogen family, have five electrons in their valence shell, outer energy shell. This includes Nitrogen, Phosphorus, Arsenic, Antimony, and Bismuth.

Answer 4

Arsenic, (As), in its ground state... and many other Ions, like Ga(-2)

Answer 5

It would be 1s22s22p63s23p2= 14 electrons total and 4 in the 3rd level so it is Silicon.

Answer 6

Strontium and rubidium have five electron shells/levels.

Answer 7

The element with 5 energy levels is likely to be Vanadium, which has 23 protons in its nucleus, leading to 5 electron energy levels according to the electron configuration of its atoms.
