Periodic Trends and Atomic Properties

In general, what is the trend in atomic radius as you go down a group in the periodic table?

• Increases

• Decreases

• Stays the same

• Fluctuates

Explain the trend in atomic radius across a period using Coulombic attraction.

• It decreases due to increased nuclear charge

• It increases due to added electron shells

• It stays the same due to constant nuclear charge

• It fluctuates due to random electron movement

Which takes more energy: removing an electron from an atom with a tight hold on its electrons or a weak hold?

• A tight hold

• A weak hold

• Both take the same energy

• It depends on the atom

Why do metals generally have low ionization energies?

• Because they have tightly held electrons

• Because they have loosely held electrons

• Because they have no electrons

• Because they are non-reactive

What property of metals is explained by their atomic structure?

• High ionization energy

• Low conductivity

• Malleability

• Non-reactivity

Which of the following is a characteristic of metals due to their atomic structure?

• High ionization energy

• High ductility

• Low malleability

• Non-conductivity

What is the relationship between Coulombic attraction and ionization energy?

• Stronger attraction means lower ionization energy

• Stronger attraction means higher ionization energy

• Weaker attraction means higher ionization energy

• No relationship

Which factor does not affect ionization energy?

• Atomic radius

• Electron configuration

• Number of neutrons

• Nuclear charge

What is the relationship between nuclear charge and ionization energy?

• Higher nuclear charge means lower ionization energy

• Higher nuclear charge means higher ionization energy

• Lower nuclear charge means higher ionization energy

• No relationship

Explain the trend in electronegativity across a period in terms of atomic structure.

• Increased atomic radius and decreased Coulombic attraction.

• Decreased atomic radius and increased Coulombic attraction.

• Increased atomic radius and increased Coulombic attraction.

• Decreased atomic radius and decreased Coulombic attraction.
