Chem 4.2 Part 4 Bohr Model Representations of Atoms

Which of the following statements is true about the Bohr model of the atom?

• It accurately describes the behavior of all electrons in an atom.

• It is a simplified model that helps explain some properties of atoms.

• It shows electrons as waves rather than particles.

• It was proposed in 1923.

In the Bohr model, how many electrons can the innermost orbit hold?

• 1

• 2

• 4

• 8

Which of the following atoms can be represented with a full first energy level in the Bohr model?

• Hydrogen

• Helium

• Oxygen

• Neon

How does the Bohr model represent different energy levels in an atom?

• As waves surrounding the nucleus

• As orbits with differing distances from the nucleus

• As random paths around the nucleus

• As fixed points within the nucleus

If an atom has 10 electrons, how are these electrons distributed in the Bohr model?

• 2 in the first orbit, 8 in the second orbit

• 8 in the first orbit, 2 in the second orbit

• 10 in the first orbit

• 5 in the first orbit, 5 in the second orbit
