Neils Bohr put forward this picture of the atom.

Ask a scientist
A shell surrounding the nucleus of an atom containing electrons.
Depending upon what the scientist does, and how experienced they are, they can make between $60,000 a year to $200,000+ It is hard to define further than this as "scientist" can be a number of different specific jobs from technicians in research laboratories to the presidents of consulting firms.
Species are modified to their specific environments, and that is why they are not identical all over the world.
That was Niels Bohr
JJ Thomson
A biologist is a specific type of scientist specializing in Biology. A scientist can be any type of scientist but their specialty is not specified.
Do you have a specific scientist in mind??
The electrons circle the nucleus in specific orbits.
Scientist work with DNA simply they can have more knowledge on DNA then they already have and know how disease are developed and how they can help to treat or cure the disease.
The electrons in the atom are found on the outer rings, the limit of 2 on the first up to 8 on the valence ring. The number of the electrons found on the valence ring determines where the chemical is placed on the Periodic Table.
Bohr predicted that electrons would orbit the nucleus much like the planets orbit the sun. This is not quite true, however, as electrons are found in the electron cloud, and do not have a specific position until they are observed.his professor Rutherford knew electrons went on the outer shells. he developed the theory that electrons can move to different levels closer or farther from the nucleus.
Could you be a tad more specific? What other scientist? What research?
The electrons can only travel in certain orbits: at a certain discrete set of distances from the nucleus with specific energies. # The electrons of an atom revolve around the nucleus in orbits. These orbits are associated with definite energies and are also called energy shells or energy levels
To solve specific problems
