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

Vertical columns in the Periodic Table that categorize elements with similar chemical properties and the same number of valence electrons.

Front

What are periods in the Periodic Table?

Back

Horizontal rows in the Periodic Table that represent elements with the same number of electron shells.

Front

What is atomic radius?

Back

The distance from the nucleus of an atom to the outermost shell of electrons, typically measured in picometers.

What is the trend of atomic radius in the Periodic Table?

Back

Atomic radius increases down a group and decreases across a period from left to right.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that determine its chemical properties and reactivity.
