Periodic Table

Front

What is the periodic table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

Front

What are alkali metals?

Back

Elements in Group 1 of the periodic table, known for being highly reactive and having one valence electron.

Front

What are cations?

Back

Positively charged ions formed when an atom loses one or more electrons.

Front

What is a group in the periodic table?

Back

A vertical column in the periodic table where elements share similar chemical properties and have the same number of valence electrons.

Front

What is a period in the periodic table?

Back

A horizontal row in the periodic table that indicates the number of electron shells an element has.

Front

What are metalloids?

Back

Elements that have properties of both metals and nonmetals, typically found along the zig-zag line on the periodic table.

Front

What is the significance of valence electrons?

Back

Valence electrons determine an element's chemical properties and its ability to bond with other elements.

Front

What is a noble gas?

Back

Elements in Group 18 of the periodic table, known for being inert and having a full valence shell.

Front

What is the atomic number?

Back

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

Front

What is the difference between metals and nonmetals?

Back

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