Periodic Trends Practice

Front

What is the atom with the largest atomic radius in Period 4?

Back

K (Potassium)

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom.

Front

How does ionization energy change across a period and down a group?

Back

Ionization energy increases across a period and decreases down a group.

Front

Which atom has greater ionization energy: Cl or Si?

Back

Cl (Chlorine)

Front

Which atom has greater ionization energy: P or Ar?

Back

Ar (Argon)

Front

What is electronegativity?

Back

A measure of the ability of an atom to attract electrons.

Front

How does electronegativity change across a period and down a group?

Back

Electronegativity increases across a period and decreases down a group.

Front

What is the trend for atomic radius in the periodic table?

Back

Atomic radius decreases across a period and increases down a group.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases.

Front

What is the significance of noble gases in periodic trends?

Back

Noble gases have high ionization energies and low electronegativities, making them stable and unreactive.
