Back

Metals are the group of elements that typically form positive ions.

Front

What must an atom have to be identified as the element carbon (C)?

Back

An atom must have 6 protons to be identified as carbon (C).

Front

Which element is classified as a nonmetal?

Back

Chlorine is an example of a nonmetal.

Front

What are the physical properties of metals?

Back

Metals are shiny, malleable (can be hammered into shapes), and ductile (can be drawn into wires).

Front

What are the physical properties of nonmetals?

Back

Nonmetals are often dull, brittle, and poor conductors of heat and electricity.

Front

In which phase do most nonmetals exist at room temperature?

Back

Most nonmetals exist in the gas phase at room temperature.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons are the outermost electrons and are involved in forming bonds between atoms.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of elements organized by increasing atomic number and grouped by similar properties.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals.

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.
