Exploring Electron Motion Around the Nucleus

In summary, the reason why electrons do not stick to the nucleus of an atom is because of a strong force between them and the orbit of electrons in electron shells. This prevents the electrons from getting too close to the nucleus. More information can be found in post #2 of the forum thread provided.

Hey people,

I have beeno wondering this for a while:

If the nucleus of an atom is positively charged and the electrons are negatively charged, why don't the electrons stick to the nucleus like a magnet, why do they only have a certain distance between themselves.

If the electrons are constantly rotating around the nucleus, this means that a change in direction would cause an accelartion of the electrons. For something to accelerate it needs energy or a force. Where does this energy comes from and why it is not extinguised over the time
:rolleyes:

I guess the reason that (negative) electrons will not stick to the (positive) nucleus is because between the nucleus and the electrons, there actually exists a strong 'force' that prevents the electrons from sticking to the nucleus. Another reason will be that elecrons orbit around the nucleus in electron shells. So, there is no way that the electrons will stick on the nucleus.
 

1. What is the nucleus?

The nucleus is the small, dense center of an atom that contains most of its mass and is composed of protons and neutrons.

2. How do electrons move around the nucleus?

Electrons move around the nucleus in specific energy levels or orbitals, which are determined by the amount of energy they possess.

3. What is the role of electrons in an atom?

Electrons play a crucial role in determining the chemical and physical properties of an atom. They are involved in chemical bonding and the creation of chemical compounds.

4. Can electrons move between energy levels?

Yes, electrons can move between energy levels by either gaining or losing energy. This process is known as electron excitation or de-excitation.

5. How do scientists study electron motion around the nucleus?

Scientists use various techniques, such as spectroscopy and electron microscopy, to study and visualize the motion of electrons around the nucleus. They also use mathematical models and calculations to understand the behavior of electrons in atoms.
