Periodic Table

What are alkali metals known for?

• They are highly reactive, especially with water, and have one electron in their outermost shell.

• They are non-reactive and have a full outer shell of electrons.

• They are good conductors of electricity and have a high melting point.

• They are found in nature as noble gases.

Where are the metaloids found in the periodic table?

• In the top row

• In the bottom row

• stair step/diagonal

• In the far right column

What is the atomic number?

• The number of neutrons in the nucleus of an atom.

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

• The total number of electrons in an atom.

• The mass of an atom measured in atomic mass units.

What is the periodic table?

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

• A graphical representation of chemical reactions.

• A list of all known compounds and their properties.

• A collection of all known isotopes of elements.

What are metalloids?

• Elements that have properties of both metals and nonmetals, found along the stair-step line in the periodic table.

• Elements that are good conductors of electricity and heat.

• Elements that are typically shiny and malleable, like metals.

• Elements that are poor conductors and are usually gases at room temperature.

What is the name of group number 1?

• alkali metals

• alkaline earth metals

• noble gases

• halogens

What is a period in the periodic table?

• A vertical column of elements in the periodic table, indicating similar chemical properties.

• A horizontal row of elements in the periodic table, indicating the number of electron shells.

• A grouping of elements that have the same atomic number.

• A section of the periodic table that contains only metals.

What are halogens?

• Elements found in group 17 of the periodic table, known for their reactivity and tendency to form salts with metals.

• Elements found in group 1 of the periodic table, known for their high conductivity and malleability.

• Elements that are gases at room temperature and are known for their low reactivity.

• Elements found in group 16 of the periodic table, known for their ability to form oxides with metals.

What are the noble gases?

• A group of reactive gases found in group 17 of the periodic table.

• A group of inert gases located in group 18 of the periodic table, including Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).

• A collection of metals that are highly conductive and located in group 3 of the periodic table.

• A set of gases that are commonly used in lighting and are found in group 1 of the periodic table.

A grouping of elements based on similar chemical properties, arranged by columns in the periodic table; also known as a group.

• family

• series

• period

• cluster
