What is the Bohr Model of the Atom?

• It describes the nucleus of an atom.
• It demonstrates that electrons orbit an atom within specific energy levels.
• It focuses on the arrangement of protons and neutrons in the nucleus.
• It explains the behavior of atoms in chemical reactions.

If 0.9 eV was absorbed by an atom than the amount of energy that would be released would be _____.

• greater than 0.9 eV
• less than 0.9 eV
• 0.9 eV
• We need more information

If frequency is increased than the speed of light would

• Increase, they are positively correlated
• Decrease, they are negatively correlated
• Stay the same, speed of light is independent of the frequency.

If wavelength is increased than the frequency would

• Increase, they are positively correlated
• Decrease, they are negatively correlated
• Stay the same, wavelength is independent of the frequency.

What is the significance of the hydrogen emission spectrum in the context of the Bohr model? A) It confirms the existence of neutrons in the hydrogen atom. B) It provides evidence for quantized electron energy levels in atoms. C) It determines the mass of the electron. D) It explains the behavior of protons in the hydrogen atom.

• Confirmed the existence of electrons
• Provided evidence for quantized electron energy levels in atoms
• explained the behavior of neutrons
• Bohr never looked at the hydrogen emission spectrum
