why are there fewer electrons closer to the nucleus?

Question

why are there fewer electrons closer to the nucleus and more electrons farther away from the nuecleus?

Answer 1

It has to do with the fact that the electrons need to keep a certain distance from each other. Negatively charged particles sich as electrons repel each other, but the positively charged protons in the nucleus attract them. This balance of charges results in the electrons orbiting in shells, held there by a balanced electrical force.

The further away from the nucleus an electron orbits, the more space there is in that shell to orbit in, without bumping into another electron. So that is why the outer shells can hold more electrons than the inner shells.

If you could see an atom, it would look a little like a tiny center of balls surrounded by giant invisible bubbles (or shells). The electrons would be on the surface of the bubbles, constantly spinning and moving to stay as far away from each other as possible. Electrons are held in their shells by an electrical force.

Electrons usually remain a constant distance from the nucleus in precise shells. The shell closest to the nucleus can hold two electrons. The next shell can hold up to eight. The outer shells cans hold even more.

Answer 2

The electrons having the same electrical charge repel each other. The closer to the nucleus the smaller the orbit so there is not as much space for them to occupy. To change orbit an electron does change energy level but it is the charge which limits the number in each orbit level.

Answer 3

It is related to the Pauli exclusion principle (part of quantum mechanics). You can't have electrons in the same state. The further out you are, the more states are possible.

Answer 4

because there are things called shells. each shell have a certain energy level. the innermost shell can only hold 2 electrons whilst the second can hold 8 and so on

Answer 5

the electrons are on the outside because thats where the electron cloud is obviously because they keep the pull of the object even, or they surround the protons to keep the pull just right. get what im saying.

Answer 6

Energy level. Electrons are like fast dogs on a leash. They run around and around and if they meet another dog? who knows what happens? lol i on know?

Answer 7

basic physics, well wats in the nucleus, protons and neutrons,
and what charge do protons have, positive

what charge do electrons have , negative

and what happens with positive and negative charges, i leave this one for you to work out , theres your ans

Answer 8

I dont remember but i think it is because of the energy level.

Answer 9

science is over rated
