Respuesta :
each electron in a atom follows a defined circular path around the nucleus
Explanation:
- Neils Bohr in 1913 put forward a model of the atom based on quantum mechanics.
- He suggested that extranuclear part of an atom contains electrons in specific spherical orbits (shells or energy levels) around the nucleus.
- As one moves outwards from the nucleus, the energy of the energy level increases.
- The concept is based on the premise that electrons can only move round the nucleus in certain permissible orbits called energy levels.
- The defined circular path is called an orbit or energy level.

Answer:
Option c)each electron has a defined amount of energy that can be defined by a set of numbers
Explanation:
The quantum theory states that electrons possess different energies and different and opposite spin numbers. It also states that each electron is described by a set of numbers. It also states that electrons have different energy levels and can be promoted to higher levels. The levels are known as orbitals.
