Modern Atomic Theory

What does an orbital represent?

• the limits of the electron location

• the probability of the electron location

• the circular path that an electron travels around the nucleus

• the minimum distance between the electron and the nucleus

Light is emitted when electrons

• move from one atom to another.

• collide with one another, releasing energy.

• move from a lower energy level to a higher energy level.

• move from a higher energy level to a lower energy level.

Which occurs if an electron transitions from n = 5 to

n = 2 in a hydrogen atom?

• Energy is absorbed, and visible light is emitted.

• Energy is released, and visible light is emitted.

• Energy is released, and visible light is not emitted.

• Energy is absorbed, and visible light is not emitted.
