What is the general trend of electronegativity in the periodic table?

Back

Electronegativity increases from left to right and decreases from top to bottom.

Front

What is the definition of a valence electron?

Back

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

Front

What is the significance of the periodic table's groups?

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 ion?

Back

An ion is an atom or molecule that has gained or lost one or more electrons, resulting in a net charge.
