Periodic Table and Atomic Structure Review

Vocabulary flashcards reviewing periodic table groups, valence electrons, atomic numbers, and periodic properties based on the worksheet.

Valence electrons

Electrons in an atom whose count can vary from 0 to 8.

Atomic number

The number that indicates not only the number of protons in an element, but also its number of electrons.

Valence octet

The configuration achieved when an element possesses 8 valence electrons.

Alkaline earth metals

The elemental family comprising the Group 2 elements.

Transition family

The family of elements to which titanium ($Ti$) belongs.

Halogens

The chemical family whose elements each have 7 valence electrons.

Lanthanide and actinide series

A group also designated as rare earth elements because they comprise less than $0.01\%$ of the Earth's elements.

Synthetic elements

All elements located beyond uranium on the periodic table.

Periodic properties

The tendency of elemental properties to repeat at regular intervals across the periodic table.
