Periodic Table Properties

Front

What is the 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 are alkali metals?

Back

Alkali metals are elements in Group 1 of the periodic table, known for being highly reactive, especially with water, and are soft enough to cut with a knife.

Front

What group do halogens belong to?

Back

Halogens are in Group 17 of the periodic table.

Front

What is a transition metal?

Back

Transition metals are elements found in Groups 3-12 of the periodic table, characterized by their ability to form variable oxidation states and colored compounds.

Front

Which element has similar properties to sulfur (S)?

Back

Oxygen (O) has similar physical and chemical properties to sulfur (S).

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties, allowing for predictions about element behavior.

Front

What are noble gases?

Back

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

Front

What is the trend of atomic radius across a period?

Back

The atomic radius decreases across a period from left to right due to increasing nuclear charge, which pulls electrons closer to the nucleus.

Front

What is the trend of atomic radius down a group?

Back

The atomic radius increases down a group due to the addition of electron shells.
