When a substance changes but still retains its original properties, the change is called a physical change. If it didn't retain its original properties, then it went through a chemical change.
physical change
A substance that cannot be broken down into simpler parts is called an element. Elements are the basic building blocks of matter and consist of only one type of atom. They are represented on the periodic table and include substances like hydrogen, oxygen, and gold. Each element retains its unique properties and cannot be chemically transformed into a simpler substance.
A substance that is formed from one type of atoms with a characteristic set of physical and chemical properties is called an element.
Chemical and physical properties
When a change in matter alters the basic nature of a substance, it is called a chemical change. In a chemical change, the substances involved react to form new substances with different properties than the original ones.
The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms is called a molecule. Each molecule is made up of one or more atoms chemically bonded together.
The smallest particle of a substance that still retains all the chemical properties of that substance is called a molecule. In the case of elements, the smallest particle is an atom, which retains the unique properties of that element. Molecules are made up of atoms bonded together in specific arrangements that determine the chemical behavior of the substance. Therefore, the smallest particle of a substance that is still that substance does indeed possess all the properties of that substance.

Chemical reaction.
The smallest part of matter that retains its own chemical properties is called a(n) _______.
The result is called a mixture. Mixtures are physical combinations of two or more substances where each substance retains its own identity and properties.
When a new substance is formed with different properties than the original substance, it is called a chemical reaction. Chemical reactions involve the breaking and forming of chemical bonds between atoms to create new substances with unique properties.
That process is called a chemical reaction.
The smallest part of substance that still retains the properties of that compound is called an atom. All things are made of atoms.
A compound that has the same properties as the elements that formed it is called a pure substance. Each element retains its chemical properties within the compound, but the compound itself may have different physical and chemical properties compared to its individual elements.
The change of one substance into a new substance is called a chemical reaction. In a chemical reaction, the atoms of the original substances rearrange to form new molecules with different properties.
