Periodic Table (Physical Science)

Front

What is the modern periodic table arranged by?

Back

The modern periodic table is arranged by order of increasing atomic number.

Front

What is a vertical column in the periodic table called?

Back

Group

Front

What is a property of Halogens?

Back

Halogens are extremely reactive.

Front

What do elements in the same group have in common?

Back

Elements in the same group have properties that are similar to each other and behave the same.

Front

What are metals?

Back

Metals are elements that form positive ions by losing electrons during chemical reactions. They are lustrous, malleable, ductile, and good conductors of heat and electricity.

Front

What is the atomic number?

Back

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

Front

What are periods in the periodic table?

Back

Periods are horizontal rows in the periodic table that indicate the number of electron shells in the elements.

Front

What are nonmetals?

Back

Nonmetals are elements that typically gain electrons during chemical reactions and have properties opposite to metals.

Front

What is the significance of valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom and determine how the atom interacts with other atoms.

Front

What are alkali metals?

Back

Alkali metals are highly reactive metals found in Group 1 of the periodic table, known for having one valence electron.
