Explanation:
Answer:
Bohr thought that electrons orbited the nucleus in circular paths; whereas in the modern view atomic electron structure is more like 3D standing waves. Bohr built upon Rutherford's model of the atom. ... He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies.

A hypothesis is a working explanation, where a theory is a well established explanation. So really hypothesis is a more of a "guess and check" "work in progress" and a theory is like a summary of overall explanation of the observed behavior. hope this helps
