GA S8P1e: Exploring Atoms and the Periodic Table

Front

What determines the position of an element in the periodic table?

Back

The atomic number of an element determines its position in the periodic table.

Front

What does the number of protons in an atom determine?

Back

The number of protons determines the identity of an element.

Front

What is the role of neutrons in an atom's nucleus?

Back

Neutrons stabilize the nucleus by offsetting the repulsive forces between protons.

Front

Where are metals located in the periodic table?

Back

Metals are found on the left side of the periodic table.

Front

Where are nonmetals located in the periodic table?

Back

Nonmetals are found on the right side of the periodic table.

Front

Why do elements in the same group of the periodic table have similar chemical properties?

Back

They have the same number of valence electrons.

Front

What is an atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom.

Front

What is 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 difference between metals and nonmetals?

Back

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

Front

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number and properties, helping predict their behavior.
