Periodic Table of Elements

Front

What is the main arrangement principle of the periodic table?

Back

Elements are arranged in increasing atomic number from left to right.

Front

Where are nonmetals primarily located on the periodic table?

Back

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

Front

What do elements in the same group of the periodic table have in common?

Back

They have the same number of valence electrons.

Front

True or False: Elements within a group have similar properties.

Back

TRUE

Front

True or False: Elements in the same group have the same number of energy levels.

Back

FALSE

Front

What is a group in the context of the periodic table?

Back

A group is a vertical column in the periodic table where elements share similar chemical properties.

Front

What is a period in the context of the periodic table?

Back

A period is a horizontal row in the periodic table that indicates the number of energy levels of the elements.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that determine its chemical properties.

Front

What is the significance of atomic number in the periodic table?

Back

The atomic number represents the number of protons in an atom and determines the element's identity.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, typically found along the zig-zag line on the periodic table.
