The building blocks of matter


Elements


The smallest particle of an element


atom


The negatively charged part of an atom


electron


A combination of elements


compound


The part of an atom with no charge


Neutron


The combination of substances where the materials can easily be separated.


A mixture


This is a combination where one substance dissolves in another substance and cannot be easily separated.


A solution


What is the name of the substance that will dissolve in a solution? (ex. chocolate powder)


The Solute


What is the substance the solute will dissolve into? (ex. the milk)


The solvent


When the solvent has taken all the solute it can, we say it has become______? (ex. no more chocolate can be added to the milk)


Saturated


The amount of space an object takes up describes what physical property?


Volume


The amount of matter an object is made of can be described as what?


Its Mass


If the mass of an object is divided by its volume, what physical property can you determine?


Its Density


If I have a 3 inch bar of iron and a 10 inch bar of iron, what physical property will be the exact same for both?


Density


Name 3 physical properties that are unique to metals


Answers will vary


This type of phase change occurs when gas particles are cooled.


Condensation


Particles are packed closely together during what phase of matter


Solid


What causes the particles of a substance to move faster, farther apart, and change form?


Heat


What is the name for when water particles begin to move with enough speed to become a gas?


Evaporation


Give an example of condensation


cloudsdew on the groundfogdroplets on a cold glass of water


What is the name given to the organized chart that lists all known elements?


The Periodic Table


Elements located in the same column of the Periodic Table have similar what?


Chemical Properties


How many elements are in a molecule of H2O?


2 - Hydrogen and Oxygen
