Answer:
false
Explanation:
As atoms of the same element have the same chemical properties because they have the same number of electrons. The only differences between atoms of the same element are the number of neutrons and the mass number.
hope this helps :)
Answer is: D.The viewer travels through the electron cloud, then the nucleus, and then the electron cloud again.
Atom is composed of the nucleus and the electron cloud.
Protons (positive particles) and neutrons (neutral particles) are in the nucleus of an atom and electrons (negative particles) are in the electron cloud.
Nucleus is in the centar of the atom atom and electron cloud is surrounding it.
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.
The mass isnt relevant
520 - 120 = 400
400 / 8 = 50
