Step-by-step explanation:

Rutherford → He said that all positive charges were found in the central nucleus.

Rutherford in 1909 , explained through his model that an atom is mostly an empty space with with electrons around the nucleus where all the positive charge is located.

Thomson → He theorized that electrons were embedded in the positive sphere, like a chocolate chip cookie.

Thomson in 1904 , explained through his model that in an atom is a positive sphere of on which electrons are embedded similar plums on the plum pudding. Also an atom is electrically neutral specie.

Bohr → He believed electrons were in fixed orbits

Bohr in 1913 , explained through his model that in an atom , electrons revolves around the nucleus of an atom in a fixed orbits with foiced amount of energy which he named shells.

Democritus → He named the atom

A Greek philosopher who has used the term atom to describe the smallest u it of matter.
