Periodic Table II (Physical Science)

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 does the atomic number represent?

Back

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

Front

What are groups in the periodic table?

Back

Vertical columns in the periodic table that group elements with similar chemical properties.

Front

What are periods in the periodic table?

Back

Horizontal rows in the periodic table that indicate the number of electron shells in the elements.

Front

Which group contains the halogens?

Back

Group 17 of the periodic table.

Front

What is the significance of group 2 elements?

Back

They are alkaline earth metals, known for being reactive and having two electrons in their outer shell.

Front

What is the difference between metals and nonmetals?

Back

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

What are noble gases?

Back

Group 18 elements that are inert and have a full valence shell, making them very stable.
