Properties of Matter
Density and mass are this type of property
Physical property
When2 or more atoms combine they create this
A molecule
A change in matter that creates new substances
Chemical changes or reactions
Bubbles or fizzing during a chemical reaction is an indication that this is being created and released.
What is a gas
Located along the stair step line on the periodic table
What are metalloids
Luster and malleability is this type of property
Physical property
H2O and CO2 are these type of molecules
What is compound
This type of change only changes the appearance and not the chemical composition of a substance
physical change
2 clear liquids were combined to create a chemical reaction. Evidence of the reaction was the production of a new solid substance.
What is a precipitate
Mostly solid, malleable, good conductors
What are metals
Reactivity and flammability
Chemical Property
H2 , Cl3, and O3 are this type of molecule
What is an element or elemental molecule
Digestion and decomposition are this type of change
Chemical
The formula for Glucose is C6H12O6
How many elements are in the formula?
Three
The joining of these two subatomic particles leads to the atom's atomic mass
What are Protons and Neutrons
Ability to rust or tarnish
chemical property
Atoms seek this subatomic particle and thus form molecules to attain it.
What arevalence electrons
Photosynthesis is this type of change
Chemical change
How many atoms are in the formula
Na2SO4
7 atoms
Which of the following does not belong and why?
Ca
CO
Co
Cl
CO because it is a compound and the others are elements
Type of Property that describes the appearance of the substance only and not its chemical composition
Physical Property
This is the total number of atoms in the formula C6H12O6
What is 24 atoms
Name all 6 clues that determine a chemical reaction
A new odor, color, gas, light, temperature, precipitate
This must occur in every chemical reaction
What is a new substance forms
Which does not belong and why?
Density, Flammability, Luster, Ductility
Flammability because it is a chemical property and the others are physical properties
