Periodic Table Exam Review

Front

What is ionization energy?

Back

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

Front

Which element has a higher ionization energy: Cesium or Chlorine?

Back

Chlorine has a higher ionization energy than Cesium.

Front

What is the trend of ionization energy across a period in the periodic table?

Back

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

Front

What is the trend of ionization energy down a group in the periodic table?

Back

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

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

Which type of elements have the largest atomic radius?

Back

Metals have the largest atomic radius compared to nonmetals and metalloids.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

How many valence electrons does Potassium (K) have?

Back

Potassium (K) has 1 valence electron.

Front

What is electronegativity?

Back

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

Front

Which elements have the same number of valence electrons?

Back

Elements in the same group of the periodic table have the same number of valence electrons.
