Answer:
Bohr's model
Explanation:
Rutherford's experimental evidence best supports the Bohr's model. Recall that in the Bohr's model, the Rutherford model was regarded as a fundamental stepping stone.
Experimental evidence from the Bohr's model shows that the atom is not a sphere of positive charges in which negative charges were embedded. It would have been impossible for Neils Bohr to build the quantum theory from such a model.
Hence, the nuclear theory of Rutherford provided a fundamental stepping stone and experimental backup for the Bohr's model of the atom.
All other models mentioned in task 1 (Dalton, Thompson and Bohr) all mention the fact that the atom is made of particles. Thompson effectively described the particles as negative and positive in nature. Bohr took the idea further by proposing that the negative particles (electrons) were actually found in energy levels that are quantized.
Answer:
D. The noble gas configuration has been reached.
Explanation:
I think the best one is B
Answer:
One single orbital can hold the maximum of 2 electrons.
Explanation:
The 2 electrons must have opposing spins otherwise they would have the same four quantum numbers, which is forbidden.
- One electron would spin up
- The other would spin down
This would tell us that each subshell would have double the electrons per orbital
