What is the Periodic Table?

Back

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

What defines a period in the Periodic Table?

Back

A horizontal row in the Periodic Table where elements have the same number of electron shells.

Front

What defines a group in the Periodic Table?

Back

A vertical column in the Periodic Table where elements have similar chemical properties due to having the same number of valence electrons.

Front

What are noble gases?

Back

Elements in Group 18 of the Periodic Table that are chemically stable and non-reactive under standard conditions.

Front

What is the significance of 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 variable oxidation states and colored compounds.

Front

What is the difference between metals and nonmetals?

Back

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

Front

What is an isotope?

Back

Atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

What is the role of valence electrons?

Back

Valence electrons are the outermost electrons of an atom and are involved in chemical bonding.

Front

What is a chemical bond?

Back

A lasting attraction between atoms that enables the formation of chemical compounds.
