Periodic Trends Review Game

Front

What is a periodic trend?

Back

A periodic trend is a pattern or tendency observed in the properties of elements as you move across or down the periodic table.

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

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state. It generally increases across a period and decreases down a group.

Front

Which group of elements is known for being highly reactive and why?

Back

The Alkali metals are highly reactive because they have one electron in their outermost shell, which they readily lose to form positive ions.

Front

What are halogens?

Back

Halogens are the elements found in Group 17 of the periodic table. They are known for being highly reactive nonmetals.

Front

What is the significance of the noble gases?

Back

Noble gases are located in Group 18 of the periodic table and are known for their lack of reactivity due to having a full valence shell.

Front

What is the chemical symbol for Silicon?

Back

The chemical symbol for Silicon is Si.

Front

How does electronegativity change across a period?

Back

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

Front

What is the trend of atomic size as you move down a group?

Back

As you move down a group in the periodic table, atomic size increases due to the addition of electron shells.

Front

What is the relationship between ionization energy and atomic radius?

Back

Generally, as atomic radius increases, ionization energy decreases because the outer electrons are further from the nucleus and are less tightly held.
