Honors Periodic Trends Showdown

Front

What is atomic radius?

Back

Atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons. It generally increases down a group and decreases across a period.

Front

Which element has the largest atomic radius among potassium, rubidium, francium, and cesium?

Back

Francium has the largest atomic radius.

Front

What trend occurs 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

How does electronegativity change as you move down group 16 in the periodic table?

Back

Electronegativity decreases as you move down group 16.

Front

Which element has a lower electronegativity value: Zr or Ag?

Back

Zr has a lower electronegativity value than Ag.

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 element requires less ionization energy to remove an electron: O or S?

Back

S requires less ionization energy to remove an electron than O.

Front

What trend occurs in ionization energy as you move across a period in the periodic table?

Back

Ionization energy generally increases as you move from left to right across a period.

Front

Which element has a larger radius: P or Sb?

Back

Sb has a larger radius than P.
