This is anything that has mass and takes up space.
What is matter?
This is the smallest particle, the building block of matter.
What is an atom?
This is matter with a composition that is always the same.
What is a substance?
This is two or more atoms chemically combined in a set ratio.
What is a compound?
These are the 3 parts of an atom, their charges and where they are located.
What is a proton is positive and found in the nucleus, neutron is neutral and found in the nucleus and an electron is negative and found in the electron cloud?
This is the definition of a physical property.
What is a characteristic of matter that you can observe or measure without changing the identity of the matter?
This is the amount of matter in an object.
What is mass?
These are 5 examples of physical properties.
What are state of matter, mass, volume, boiling point, melting point, solubility, density, and conductivity?
Explain how solids, liquids and gases differ.
Solid- particles close together and vibrate Liquid- particles touch but can slide past each other Gas- particles move very quickly and fill their container.
This is the ability of one substance to dissolve in another.
What is solubility?
This is a change in size, shape, form, or state of matter in which the matter’s identity stays the same.
What is a physical change?
This is what a solid will eventually become, when thermal energy is added.
What is a liquid?
This is the change of a solid directly to a gas, without first becoming a liquid.
What is sublimation?
This is occurs when the particles are moving slowly enough for attractive forces to pull the particles close together.
What is condensation?
This tells us that the mass before and after a physical change is the same.
What is Conservation of Mass?
This is a characteristic of matter that can be observed as it changes to a different type of matter.
What is a chemical property?
This is the name for the chemical formulas to the left of the arrow in a chemical equation.
What are the reactants?
This must be balanced on both sides of a chemical equation.
What is the number of atoms of each element?
These are the three things that can affect the rate of a chemical reaction.
What are: -higher temperature -concentration -surface area ?
These are four signs of chemical change.
What are: -formation of bubbles - change in odor -change in color -change in energy ?
This is the first step in balancing a chemical equation.
What is writing down each element’s symbol and counting how many atoms there are of each type?
A penny turning green is an example of this.
What is a chemical change?
This is the number of Hydrogen atoms the following formula H 2 O.
What is two?
This physical property of copper explains why it is often used in electrical wiring.
What is conductivity?
These are three size-dependent properties.
What are -mass -volume -weight ?

Properties of Matter Matter - anything that has mass and takes up space. Mass - the measurement of the amount of matter in an object. We use a balance.
