periodic table 2

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 groups in the periodic table?

Back

Columns in the periodic table that contain elements with similar chemical properties.

Front

What are periods in the periodic table?

Back

Rows in the periodic table that represent elements with the same number of electron shells.

Front

What is a halogen?

Back

Elements found in Group 17 of the periodic table, known for being highly reactive nonmetals.

Front

What is a metalloid?

Back

An element that has properties of both metals and nonmetals.

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 atomic size?

Back

The distance from the nucleus of an atom to the outermost shell of electrons.

Front

What is reactivity in terms of elements?

Back

Reactivity refers to how readily an element combines with other substances to form compounds.

Front

What are noble gases?

Back

Elements in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

What is the difference between metals and nonmetals?

Back

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