Matter Types
This is a pure substance made of only one type of atom.
What is an Element?
This type of reaction absorbs heat from its surroundings.
What is an endothermic reaction?
These are the three subatomic particles that make up an atom.
What are protons, neutrons, and electrons?
This is the substance that is dissolved in a solution.
What is a solute?
The otter most shell where electrons orbit around the nucleus.
What is the valance shell?
This type of mixture has a uniform composition throughout.
What is a homogeneous mixture?
These indicate a chemical change has occurred: a color change, gas/odour production, heat/light/sound produced, a precipitate formation, or is difficult to reverse.
What are the five clues of a chemical reaction?
This term describes the outermost shell of an atom where electrons reside.
What is the valence shell?
This is the liquid in which a solute is dissolved.
What is a solvent?
Stirring and heating (agitating) allow more solute to dissolve in the solvent.
How to create a supersaturated solution?
A combination of two or more substances that retain their individual properties.
What is a mixture?
The substances that are present before a chemical reaction occurs.
What are reactants?
This is the number of protons in the nucleus of an atom, which determines the element.
What is the atomic number?
This term describes a solution that contains the maximum amount of solute that can dissolve at a given temperature.
What is a saturated solution?
This is the smallest unit of an element that retains the properties of that element.
What is an atom?
This is a type of mixture where the components are not evenly distributed.
What is a heterogeneous mixture?
This type of reaction releases heat to its surroundings.
What is an exothermic reaction?
This type of bonding involves the sharing of electron pairs between atoms.
What is a covalent bond?
This process can be used to increase the concentration of a solution.
What is evaporation?
This term describes a solution with a low concentration of solute.
What is a dilute solution?
This type of matter consists of two or more different elements chemically bonded together.
What is a compound?
The substances formed as a result of a chemical reaction.
What are products?
This type of bond occurs when electrons are transferred from one atom to another.
What is an ionic bond?
This occurs when more solute is added to a saturated solution at high temperatures and then cooled.
What is supersaturation?
This term refers to the process of a solute dissolving in a solvent.
What is dissolution (dissolving)?
