|
Physical property of matter |
Describe the physical appearance or composition of a substance |
PHYSICAL |
|
Physical properties of matter |
Boiling / condensing Point, melting / freezing point, malleability, ductility, color, State, solubility, Crystal formation, and conductivity |
There are 9 of them |
|
Boiling / condensing point |
Temperature at which boiling or condensing occurs |
N/a |
|
Melting / freezing point |
Temperature at which melting or freezing occurs |
N/a |
|
Malleability |
Ability to be beaten or rolled into sheets without crumbling |
Think of metal spoons and how you can bend them forward and back |
|

Solid, liquid, or gas |
N/a |
|
Solubility |
Ability to dissolve in a liquid |
DisSOLve SOLubility |
|
Crystal formation |
Crystalline appearance |
Self-explanatory |
|
Conductivity |
Ability to conduct heat or electricity |

|
Physical change |
Involves a change in physical properties of a substance without changing the type of matter; no new substance is created during a physical change, although the matter takes a different form |
Changing physically |
|
Chemical property of matter |
A property that describes the ability of a substance to change into a new substance or substances |
More detail Than Physical |
|
Chemical properties of matter |
Ability to burn, flash point, behaviour in air, reaction with water, and reaction to Heating |
There are five of them |
|
Ability to burn |
Combustion (flame, heat, light) |
Burst into flames comBUSTion |
|
Flash point |
Lowest temperature at which a flammable liquid will ignite in air |
Justice League Flashpoint paradox Aquaman is in Justice League Aquaman equals water Flash equals fire Superman can fly equals air |
|
Behaviour in Air |
Tendency to degrade, react, or tarnish |
How does it act in air |
|
Reaction with water |
Tendency to corrode or dissolve |
How does it react in water |
|
Reaction to Heating |
Tendency to melt or decompose |
How does it react with heat |
|
Clues that chemical change has occurred |
Heat or light is given off, bubbles of gas are given off, precipitate forms when two liquids combine, color change, and change is not easily reversed as the object reacting has become something new |
There are five of them |
|
Pure substance |
Made up of only one kind of matter and has a unique set of properties |
Pure |
|
Element |
Pure substance that cannot be broken down into any simpler substance |
Elements from the Earth |
|
Compound |
Pure substance that is made from two or more elements that are combined chemically |
Compound words |
|
Mixture |
Combination of pure substances |
Mix |
|
Homogeneous mixture |
Mixture that looks the same throughout and the separate components are not visible |
Homo means same |
|
Solution |
Homogeneous mixture |
SOLution disSOLving when something dissolves it all looks the same |
|
Heterogeneous mixture |
In which different parts of the mixture are visible |
Hetero means different |
|
Suspension |
Heterogeneous mixture in which a cloudy mixture is formed when the particles of one substance are held within another substance |
Suspension is temporary Particles are only partially visible |
|
Mechanical mixture |
Heterogeneous mixture which may contain several solids combined together |
Machines are clunky and not smooth |
|
John Dalton's atomic theory |
All matter is made of atoms All atoms of a given element are the same Compounds are formed when different atoms combine in a fixed proportion Chemical reactions involve the rearrangement of atoms |
There are four points |
|
Proton (symbol relative mass charge and location) |
p+ 1836 1+ Nucleus |
There are usually less protons than neutrons |
|
Neutron (symbol relative mass charge and location) |
n0 1837 0 Nucleus |
There are usually more neutrons than protons |
|
Electron (symbol relative mass charge location) |
1 1- e-11-In shells surrounding nucleus In shells surrounding nucleus |
Electrons are the only ones that can move around therefore they must be very light |
|
Valence shell |
Outermost shell of an atom |
A vail is put on the outside of a face |
|
Periodic table |
Contains a standard set of symbols to represent the elements; laid out in a specific pattern (developed by Dmitri Mendeleev in 1869) |
No hint needed |
|
Atomic number |
Number of protons and electrons in an atom |
N/a |
|
Atomic mass |
Measure of average mass of an atom of an element; found in the nucleus (protons and neutrons) |
Mass of atoms |
|
Ion |
An atom with a charge |
Don't overthink |
|
Metals ... electrons to form ... ions called ... |
Lose Positive Cations |
Think about the placement of metals on the periodic table |
|
Non metals ... electrons to form ... ions which are called ... |
Gain Negative Anions |
Think of the placement of non-metals on the periodic table |
|
Polyatomic ion |
Group of atoms with a charge |
Poly means multiple |
