One way in which elements differ from each other is the structure of the electron cloud in each element’s atoms. In an electron cloud, an electron that is farther away from the nucleus has
Answer
A
a greater charge than an electron near the nucleus.
B
a smaller charge than an electron near the nucleus
C
a higher energy than an electron near the nucleus.
D
a lower energy than an electron near the nucleus.
Explanation
Electrons farther from the nucleus are generally in higher energy levels than electrons closer to it. The electron’s charge does not change with its distance from the nucleus, so the correct choice is C, “a higher energy than an electron near the nucleus.”
