Periodic Table Families

What are Halogens?

• A group of non-metal elements in Group 17 of the Periodic Table, known for being highly reactive and forming salts with metals.

• A group of metals in Group 1 of the Periodic Table, known for being highly conductive and malleable.

• A group of noble gases in Group 18 of the Periodic Table, known for being inert and non-reactive.

• A group of transition metals in the center of the Periodic Table, known for their ability to form colored compounds.

What is a non-metal?

• Elements that are generally poor conductors of heat and electricity, and can be gases, liquids, or brittle solids.

• Elements that are good conductors of heat and electricity, typically found in solid form.

• Elements that are malleable and ductile, often used in construction.

• Elements that are typically gases at room temperature and have low boiling points.

What is a group in the Periodic Table?

• A horizontal row in the Periodic Table that contains elements with increasing atomic numbers

• A vertical column in the Periodic Table that contains elements with the same number of valence electrons and therefore similar chemical properties

• A section of the Periodic Table that includes only metals

• A category of elements that have similar physical states at room temperature

What is a metal?

• Elements that are typically shiny, good conductors of heat and electricity, and malleable.

• Elements that are dull, poor conductors of heat and electricity, and brittle.

• Elements that are gaseous at room temperature and have low density.

• Elements that are typically colorful, good insulators, and non-malleable.

What are Noble Gases?

• Elements in Group 18 of the Periodic Table that are colorless, odorless, and unreactive under standard conditions.

• Elements that are highly reactive and form compounds easily.

• Elements that are found in liquid form at room temperature.

• Elements that have incomplete outer electron shells.

What is reactivity in terms of elements?

• The ability of an element to exist in multiple states.

• The tendency of an element to undergo chemical reactions, with more reactive elements readily forming compounds.

• The measure of an element's atomic mass.

• The capacity of an element to conduct electricity.

What are Transition Metals?

• Elements found in Groups 1-2 of the Periodic Table with low densities and melting points.

• Elements found in largest family on the Periodic Table- Groups 3-12, high densities/melting points, excellent conductors, malleable/ductile, etc.

• Elements that are gases at room temperature and have low boiling points.

• Elements that are radioactive and found in the bottom rows of the Periodic Table.

What are Alkaline Earth Metals?

• A group of elements in Group 1 of the Periodic Table, known for being highly reactive and having 1 valence electron.

• A group of elements in Group 2 of the Periodic Table, characterized by being shiny, silvery-white, and somewhat reactive. Have 2 valence e- and tend to lose 2 e- when forming bonds.

• A group of noble gases that are colorless, odorless, and non-reactive under standard conditions.

• A group of transition metals known for their high melting points and conductivity.

What is a valence electron?

• An electron in the outer most electron orbital.

• An electron that is free to move in a conductor.

• An electron that is involved in chemical bonding.

• An electron located in the nucleus of an atom.

What are Alkali Metals?

• A group of elements in Group 1 of the Periodic Table, known for being soft, silvery, and highly reactive, especially with water.

• A group of elements in Group 2 of the Periodic Table, known for being hard and less reactive than alkali metals.

• A group of noble gases that are colorless and odorless, found in Group 18 of the Periodic Table.

• A group of transition metals that are known for their high melting points and conductivity.
