Based on the research of Albert Einstein, what change would most likely result in stopping the emission of electrons from this m
etal? an increase in the intensity of the light
a decrease in the intensity of the light
the use of light that has a higher frequency
the use of light that has a lower frequency
Answer: The use of light that has a lower frequency
Explanation: In order to stop the emission of electrons from the metal, the light used should be of lower frequency so that it wont be able to strike off the metal atom as effectively as it could.
When we use the light of lower frequency, the kinetic energy of the light decreases and thus it wont be able to emit much of the electrons from the metal surface.
Many of the elements on the periodic table will always form ions that have the same charge. The alkali metals (shown in yellow) always form +1 ions. The alkaline earth metals (red) always form +2 ions. The halogens (blue) always form -1 ions.
