Families of the Periodic Table

Front

What is a Noble Gas?

Back

Noble gases are a group of chemical elements that are odorless, colorless, monatomic gases with very low chemical reactivity. Examples include Helium, Neon, Argon, Krypton, Xenon, and Radon.

Front

Which elements are classified as metals?

Back

Metals are elements that are typically shiny, good conductors of heat and electricity, and malleable. They are found on the left side of the periodic table.

Front

What is an Alkaline Earth Metal?

Back

Alkaline Earth Metals are the elements in Group 2 of the periodic table. They are reactive and include Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.

Front

Identify the family that contains nitrogen and phosphorus.

Back

The family that contains nitrogen and phosphorus is called the Nitrogen Group or Group 15 of the periodic table.

Front

What is a nonmetal?

Back

Nonmetals are elements that are typically poor conductors of heat and electricity, and they can be gases, liquids, or solids at room temperature. Examples include Oxygen, Nitrogen, and Sulfur.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals. They are found along the staircase line on the periodic table. Examples include Silicon and Arsenic.

Front

What is the significance of the staircase line on the periodic table?

Back

The staircase line on the periodic table separates metals from nonmetals and indicates the position of metalloids.

Front

What are the characteristics of Alkali Metals?

Back

Alkali Metals are highly reactive, especially with water, and are found in Group 1 of the periodic table. They include Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.

Front

What is the periodic trend for atomic size?

Back

Atomic size generally increases down a group and decreases across a period from left to right due to increasing nuclear charge.

Front

Define electronegativity.

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It increases across a period and decreases down a group.
