Question

what is the arrangement of electrons in an atom when the energy level is 4​

Answer 1

Answer:

The electrons surrounding an atom are located in regions around the nucleus called “energy levels”.

An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be.

The first energy level is closest to the nucleus. The second energy level is a little farther away than the first. The third is a little farther away than the second, and so on.

Each energy level can accommodate or “hold” a different number of electrons before additional electrons begin to go into the next level.

When the first energy level has 2 electrons, the next electrons go into the second energy level until the second level has 8 electrons.

When the second energy level has 8 electrons, the next electrons go into the third energy level until the third level has 8 electrons.

When the third energy level has 8 electrons, the next 2 electrons go into the fourth energy level.

The electrons in the energy level farthest from the nucleus are called valence electrons.
