Periodic trends review (a little more challenging)

Front

What is atomic radius?

Back

The 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 in Period 4?

Back

Potassium (K) has the largest atomic radius in Period 4.

Front

What happens to atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases because you add more and more shells (energy levels) of electrons.

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 has the smallest ionization energy in Period 6?

Back

Cesium (Cs) has the smallest ionization energy in Period 6.

Front

What is the trend of ionization energy across a period?

Back

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

Front

Which element has greater ionization energy: Magnesium or Phosphorus?

Back

Phosphorus has greater ionization energy than Magnesium.

Front

Which noble gas has the largest atomic radius?

Back

Radon (Rn) has the largest atomic radius among the noble gases.

Front

What is the trend of atomic radius across a period?

Back

Atomic radius generally decreases across a period from left to right due to increasing nuclear charge pulling electrons closer to the nucleus.

Front

Why does atomic radius increase down a group?

Back

Atomic radius increases down a group because additional electron shells are added, which increases the distance between the nucleus and the outermost electrons.
