Front

What is a halogen?

Back

A group of elements in Group 17 of the periodic table, known for being highly reactive nonmetals. Example: Chlorine.

Front

What are the atoms along the staircase in the periodic table called?

Back

Metalloids, which have properties of both metals and nonmetals.

Front

What is a group in the periodic table?

Back

A vertical column in the periodic table where elements have similar chemical properties.

Front

What happens to atomic size as you move across a period in the periodic table?

Back

Atoms tend to get smaller because they have more protons that exert a stronger pull on electrons.

Front

What are semiconductors?

Back

Elements that have conductivity between metals and nonmetals, typically found in Group 14. Example: Silicon.

Front

What is the periodic table?

Back

A tabular arrangement of elements organized by increasing atomic number, showing periodic trends.

Front

What are noble gases?

Back

Elements in Group 18 of the periodic table that are inert and do not readily react with other elements.

Front

What is the significance of the atomic number?

Back

The number of protons in the nucleus of an atom, which determines the element's identity.

Front

What are transition metals?

Back

Elements found in Groups 3-12 of the periodic table, known for their ability to form various oxidation states.

Front

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, conductive, and malleable, while nonmetals are dull, insulative, and brittle.
