Bohr's Atomic Model Quiz

According to Rutherford's atomic model, why would an atom be highly unstable?

• The electrons continuously radiate energy and fall into the nucleus

• The electrons gain acceleration and move in circular paths

• The nucleus contains positively charged protons

• The atom is composed of discrete orbits of electrons

Who made modifications to Rutherford's atomic model to explain the stability of atoms?

• Niels Bohr

• James Chadwick

• Sir Isaac Newton

• Albert Einstein

What did Niels Bohr suggest about the energy levels of electrons in an atom?

• The electrons revolve in fixed orbitals

• The electrons gain acceleration and radiate energy

• The electrons are randomly scattered in the orbitals

• The electrons are composed of discrete orbits

What are the electron orbitals referred to as?

• Shells or energy levels

• Protons and neutrons

• Discrete orbits

• Nucleus and electrons
