Module 5 Review

Front

What is ionization energy?

Back

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

Front

Which element has a lower ionization energy than Scandium (Sc)?

Back

Calcium (Ca) has a lower ionization energy than Scandium.

Front

What are the rows on the periodic table called?

Back

Rows on the periodic table are called Periods.

Front

What do elements in the same group or column have in common?

Back

Elements in the same group or column have the same number of valence electrons.

Front

What is the group number of Beryllium?

Back

Beryllium is in Group 2.

Front

What are the columns in the periodic table called?

Back

Columns in the periodic table are called Groups.

Front

What is the significance of valence electrons?

Back

Valence electrons determine an element's chemical properties and its ability to bond with other elements.

Front

How does ionization energy change across a period?

Back

Ionization energy generally increases across a period from left to right due to increasing nuclear charge.

Front

How does ionization energy change down a group?

Back

Ionization energy generally decreases down a group due to increased distance between the nucleus and valence electrons.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy decreases because the outermost electrons are further from the nucleus.
