Quantum Model and EMR Practice

How many orbitals are there in the n = 3 energy level of an atom?

• 4

• 9

• 5

• 6

Each p subshell contains _____ orbitals

• 1

• 3

• 5

• 7

The Aufbau principle states that:

• electrons enter the lowest available energy level

• electrons enter one orbital at a time

• electrons enter an orbital in the highest energy level available

• electrons only enter the lowest energy level if the ones with a higher energy are full

When atoms receive energy, the electrons:

• jump to a higher energy level and fall back to a lower one, emitting energy in the form of light of a specific frequency in the process

• jump to a higher energy level and fall back to a lower one, emitting energy with a varied frequency each time

• do not absorb the energy, it gets absorbed in the nucleus instead

• jump to a higher energy level and fall back to a lower one, emitting energy in the form of heat

What is the relationship between wavelength and frequency?

• Inversely proportional

• Directly proportional

• Same

• We cannot say

If n = 3, what is the maximum number of electrons that can fit in this shell?

• 2

• 8

• 18

• 32

Which quantum number represents the shape of the orbital?

• principal quantum number

• azimuthal (angular momentum) quantum number

• magnetic quantum number

• spin quantum number

Electrons are described by quantum numbers. The principal quantum number, n, describes an electron's

• shape.

• main energy level.

• velocity.

• charge.

For the f sublevel, the number of orbitals is

• 18.
• 9.
• 5.
• 7.

For a principle quantum number, "n", equal to 2, what is the total electron capacity of that level? 

• 2
• 8
• 4
• 16
