Front

What is a single replacement reaction?

Back

A single replacement reaction is a chemical reaction where one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What are chemical families in the periodic table?

Back

Chemical families are groups of elements in the periodic table that have similar properties due to their similar electron configurations.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged ion composed of two or more atoms covalently bonded together, which acts as a single unit.
