Front

What is a balanced equation?

Back

A balanced equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during a chemical reaction.

Front

Which elements have the same number of valence electrons?

Back

Elements in the same group of the periodic table have the same number of valence electrons.

Front

What is evidence of a chemical reaction?

Back

Evidence of a chemical reaction includes the formation of a new substance, such as a gas, solid, or color change.

Front

How many valence electrons does Iodine have?

Back

Iodine has 7 valence electrons.

Front

Is silicon a metal, nonmetal, or metalloid?

Back

Front

What is a chemical reaction?

Back

A chemical reaction is a process where reactants are transformed into products, involving the breaking and forming of chemical bonds.

Front

What are valence electrons?

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 valence electrons in bonding?

Back

Valence electrons determine how an atom can bond with other atoms, influencing the chemical properties of the element.

Front

What is the periodic table?

Back

The periodic table is a tabular arrangement of elements organized by increasing atomic number, showing periodic trends in properties.

Front

What is a metalloid?

Back

Metalloids are elements that have properties of both metals and nonmetals, often used in semiconductors.
