Question 4 • TOL-202627-S1-SCI-Physical Science 1A - Zisette, Jennifer

An atom’s emission of light with a specific amount of energy confirms that

Answer
A
atoms must have a dense central mass surrounded by electrons at a distance.
B
electrons emit and absorb energy based on their position around the nucleus.
C
electrons can only be found within predicted areas surrounding the nucleus.
D
atoms are made of positive and negative charges.

Explanation

A photon of light has a specific energy when an electron moves between particular energy levels. This shows that electrons emit or absorb specific amounts of energy depending on their positions relative to the nucleus. Therefore, the best answer is B, “electrons emit and absorb energy based on their position around the nucleus.”
