Question

__________ described atoms as having a positive nucleus with electrons that have different energies at different distances from the nucleus.

Option that go in the blank:
Bohr or Dalton or Rutherford or Thomson pick one

Answer 1

Niels Bohr

Step-by-step explanation:

Niel’s Bohr described the atomic model. He in his model showed that an atom is a small positively charged nucleus. Around the positively charged nucleus, electrons orbit in separate orbits.

The electrons in the outermost shell are responsible for the properties associated with an element.

The electrons at different shells have different energy. When an electron jumps from a shell of higher energy to a shell of lower energy, energy is released.
