Question

1. choose all that apply.

which three postulates are of the bohr model of the atom?
electrons in each orbit contain a specific amount of energy.
electrons can only travel in discrete orbits at specific distances from the nucleus.
electrons can only lose energy by jumping to a higher or lower orbit.
electrons can travel in any path at any distance from the nucleus.
electrons can only gain or lose energy by jumping to a higher or lower orbit.

1. choose the best answer.

which statement is true?
the ground state is the orbital farthest from the nucleus.
electrons like to be in the ground state and can get there by releasing energy.
valence electrons are closest to the nucleus.
electrons can reside anywhere in an atom.

Explanation:

• For question 3:
• In the Bohr model, electrons in each orbit have a specific energy (quantized energy levels).
• Electrons can only travel in discrete orbits at specific distances (quantized orbits).
• Electrons gain or lose energy by jumping between orbits (energy absorption or emission during transitions).
• For question 4:
• The ground - state is the lowest energy state (closest to the nucleus, not farthest).
• Valence electrons are in the outermost shell (not closest to the nucleus).
• Electrons are in specific orbitals (not anywhere). Electrons tend to be in the ground state (lowest energy) and release energy to reach it from higher - energy excited states.

Answer:

• Question 3:
• Electrons in each orbit contain a specific amount of energy.
• Electrons can only travel in discrete orbits at specific distances from the nucleus.
• Electrons can only gain or lose energy by jumping to a higher or lower orbit.
• Question 4: Electrons like to be in the ground state and can get there by releasing energy.
