Which best explains what happens when an electron moves
from an excited state to the ground state? - THE CORRECT ANSWER-
The electron releases energy as it moves to a lower energy level.
What is released when an excited electron returns to a lower
energy state? - THE CORRECT ANSWER-electromagnetic radiation
Which transition by an electron will release the greatest amount
of energy? - THE CORRECT ANSWER-A
This image shows a stream of positively charged particles being
directed at gold foil. The positively charged particles are called
"alpha particles" and each one is like a nucleus without any
electrons.
, What is the best explanation for why a particle is striking point
X?
Alpha parti - THE CORRECT ANSWER-When the dense, positive alpha
particle passes close to a positive nucleus of gold, the alpha
particle repels and hits the screen at point X.
Which phenomena support only the particle theory of light?
Check all that apply. - THE CORRECT ANSWER-4 & 5
traveling in a straight path
photoelectric effect
Wilam made a chart to summarize the results of experiments
with the photoelectric effect.
Which best describes how to correct Wilam's error? - THE CORRECT
ANSWER-The first result should state that frequencies of light that
were lower than the frequency threshold of the metal could not
eject electrons.
What is the smallest packet of electromagnetic energy that can
be absorbed or emitted? - THE CORRECT ANSWER-a quantum
Which theory was contradicted by experiments with the
photoelectric effect? - THE CORRECT ANSWER-Visible light, regardless
of color, will cause the ejection of electrons when striking metal.
