Multiple Choice

Why is there a large jump in ionization energy 1 and 2 for Lithium?

• the valence electrons are harder to lose than core electrons

• the valence electrons are easier to lose than core electrons

Multiple Choice

What does the graph of successive ionization energies of magnesium indicate about the existence of energy levels?

• It shows no clear pattern

• It indicates energy levels exist

• It shows only one energy level

• It indicates energy levels are irrelevant

Multiple Choice

What trend is observed in the first ionization energies of group 2 elements as you move down the group?

• They increase

• They decrease

• They remain constant

• They fluctuate

Multiple Choice

As the energy level goes higher, the electrons

• have lower in energy

• are more stable

• are weaker

• are farther from the nucleus

Open Ended

Electrons tend to fill sublevels that are _______________ in energy first.

Multiple Choice

What is the maximum number of electrons that can be on the p sublevel?

• 6
• 3
• 2
• 4

Multiple Choice

What are the different blocks of the periodic table?

• s-block

• p-block

• d-block

• f-block

Multiple Choice

How many sublevels exist in the 2nd energy level?

• 1 sublevel, the s sublevel

• 1 sublevel, the p sublevel

• 2 sublevels, the s and p sublevels

• 3 sublevels, the s, p, d sublevels

Multiple Choice

Define Aufbau principle

• Sub shells (boxes) must have at least 1 e- in each orbital before placing another e- and filling

• Rule that electrons occupy the orbitals of lowest energy first

• No two electrons in the same atom can have the same set of four quantum numbers

Multiple Choice

Of the following sublevels, which is in the highest energy level?

• 4s

• 3d

• 4p

• 5s

Multiple Choice

Which is associated with more energy? 

• 2p
• 2s
• 3p
• 1s

Multiple Choice

Which orbital does the image represent?

• s

• p

• d

• f

Multiple Choice

Transition metal have variable oxidation states due to

• ability to lose electron from 3d and 4s
• ability to lose electrons from 4s
• ability to form complex ions
• ability to react with ligands

Multiple Choice

What is incorrect about this orbital diagram?

• Both arrows in the 2p box should be pointing up

• There is nothing incorrect with this diagram

• In the 2p box there should only be 1 electron in the first 2p box and one in the 2nd 2p box pointing in the same direction.

• All the arrows should be pointing up.
