Science

Question

Why does electrons doesn't get attracted to the nucleus as the nucleus is positively charged? I thought opposite opposite sign attract each other? Based on science atom particles.

Comments

erm electrons does get attracted by the nucleus. what makes you think it doesn't? :/
If you are referring to why the electrons doesn't collapse into the nucleus, that's because electrons have a certain amount of energy (kinetic energy in this case) that enables them to stay away from the nucleus at a certain distance (based on their energy levels)

Then I don't really understand how the energies enable them to stay away from the nucleus? I kinda hate science lol.

An atom has shells with different energy levels, the further the shells are from the nucleus, the higher the energy level the electrons are required to obtain for them to be staying at that particular shell. When electrons obtain energy, which in this case in the form of kinetic energy. This energy makes electrons to move a lot, thus overcoming the electrostatic force from the nucleus to a certain extent.

Oh I get it now.  NPL, u wanna write it as answer so i can 采纳？

I'm glad you understand, and thx btw ;)
