Unit 5 Summative Review

Front

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

Back

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

Front

Which group of elements is known for having similar chemical properties?

Back

Elements in the same group (column) of the periodic table have similar chemical properties.

Front

What type of radiation is the least penetrating?

Back

Alpha particles have the least penetrating power compared to beta particles and gamma rays.

Front

What property did Mendeleev use to arrange his periodic table?

Back

Mendeleev arranged his periodic table primarily by atomic weight.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom.

Front

How does ionization energy change across a period in the periodic table?

Back

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

Front

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

Back

Electronegativity increases as you move from left to right across a period.

Front

Which element has the largest atomic radius: potassium, rubidium, francium, or cesium?

Back

Francium has the largest atomic radius among these elements.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy generally decreases.

Front

What are alkali metals?

Back

Alkali metals are the elements in Group 1 of the periodic table, known for being highly reactive.
