Question

circle the appropriate word to complete each statement in questions 14 - 17. 14. electrons and protons (attract/repel) each other. 15. as an electron gets closer to the nucleus the (attraction/repulsion) to the nucleus gets (stronger/weaker). 16. for an electron to move from an energy level close to the nucleus to an energy level far from the nucleus it would need to (gain/lose) energy. 17. for an electron to move from an energy level far from the nucleus to an energy level close to the nucleus it would need to (gain/lose) energy. read this! niels bohr modified rutherfords nuclear atom model to explain how light interacted with the electrons in an atom to produce spectral lines. his model included electrons orbiting the nucleus at specific energy levels. electrons absorb energy from various sources (electricity) when they move from lower energy levels (ground state) to higher energy levels (excited states). energy is released as electrons return to their lower energy levels. 18. is energy absorbed or released for the electron transition shown in the diagram to the right? explain. electron energy and light

Explanation:

Step1: Recall charge properties

Electrons are negatively charged and protons are positively charged. Opposite charges attract.

Step2: Analyze electron - nucleus interaction

As an electron gets closer to the positively - charged nucleus, the electrostatic attraction force increases.

Step3: Understand electron energy levels

Electrons need to gain energy to move to energy levels further from the nucleus which have higher energy.

Step4: Energy change for electron movement

Electrons release energy when moving from higher to lower energy levels.

Step5: Determine energy change for diagram

Based on the direction of electron movement in the diagram (not shown here in detail but based on the principle), if moving up in energy levels, absorb; if moving down, release.

Answer:

1. attract
2. attraction; stronger
3. gain
4. lose
5. If the electron is moving from a lower - energy level to a higher - energy level in the diagram, energy is absorbed. This is because electrons need to gain energy to move to higher energy levels as per the Bohr model. If it is moving from a higher - energy level to a lower - energy level, energy is released.
