Periodic Trends Practice

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

Which direction on the periodic table does ionization energy generally increase?

Back

Ionization energy generally increases from left to right across a period and decreases down a group.

Front

What is the trend in atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group due to the addition of electron shells.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Which element has the highest electronegativity?

Back

Fluorine (F) has the highest electronegativity.

Front

What is the trend in electronegativity as you move across a period?

Back

Electronegativity generally increases from left to right across a period.

Front

What is the relationship between atomic radius and ionization energy?

Back

As atomic radius increases, ionization energy generally decreases because the outer electrons are further from the nucleus.

Front

What is the significance of a large jump in ionization energy?

Back

A large jump in ionization energy indicates that an electron is being removed from a more stable electron configuration, such as a core electron.

Front

How does the ionization energy of alkaline earth metals compare to alkali metals?

Back

Alkaline earth metals have higher ionization energies than alkali metals due to their greater nuclear charge.

Front

What is the order of increasing atomic radius for the elements: S, Co, Cs?

Back

The order of increasing atomic radius is S, Co, Cs.
