Answer:
The main difference between the two models was about the location of the electron in an atom.
Explanation:
<u>Rutherford described that:</u>
- The electrons were outside of the nucleus.
- They were equal in number to the "positiveness" of the nucleus.
- Also, He randomly placed the negative electrons outside the nucleus.
<u>Bohr improved the Rutherford model:</u>
- Bohr placed the electrons in distinct energy levels.
- Electrons only exist in fixed orbitals (shells) and not anywhere in between.
- Each shell has a fixed energy
- Rutherford explained the nucleus of an atom, while Bohr was more into the electrons and their energy levels.
Answer:
Even renewable resources can be used unsustainably. We can cut down too many trees without replanting. We might need grains for food rather than biofuels. Some renewable resources are too expensive to be widely used

Answer:
Neutral. There are equal amounts of protons or positively charged parts and electrons or negatively charged parts. The neutrons have no net charge which means this atom of chlorine is neutral.
Explanation:
Answer:
The further an electron is from the nucleus. the greater its energy level.
Explanation:
When an electron is close to the nucleus, it is at as low an energy level as it can get.
We must put energy into an electron to pull it away from the attraction of a nucleus.
So, electrons that are further from the nucleus are at higher energy levels.
Answer:
describes properties characteristic of no more than two electrons in the vicinity of an atomic nucleus or of a system of nuclei as in a molecule
