Multiple Choice

What is the trend observed in the successive ionization energies of chlorine?

• Decreasing energy

• Constant energy

• Increasing energy

• Fluctuating energy

Multiple Choice

Why does it take more & more energy to remove successive e-?

• Because there are more electrons to remove

• Because the nucleus has more protons

• Because there are less electrons for the protons to hold on to

• Because the atom becomes larger

Multiple Choice

When would we see the highest IE?

• When we break a full energy level

• When electrons are paired

• When the atom is unstable

• When the atom has fewer protons

Multiple Choice

Nitrogen is an atom with 5 valence electrons. Oxygen is an atom with 6 valence electrons. How many valence electrons does Sulfur have?

• 5

• 6

• 11

• 4

Multiple Choice

What happens to the atomic radius when a cation is formed?

• Increases

• Decreases

• Remains the same

• Varies depending on the element

Multiple Choice

What happens to the atomic radius when an electron is added to an atom to form an anion?

• It decreases

• It stays the same

• It increases

• It becomes negative

Multiple Choice

As you move down a group, atomic radius increases because - 

• you add more and more neutrons

• you add more and more protons

• you add more and more shells (energy levels)

• you add more atomic mass
