Chemistry Midpoint Flashcards
Pure substances
A substance where all the particles that make up a substance stay the same
Pure substances split into?
Elements and Compounds
Mixtures
Combination of 2 or more substances that are NOT chemically bonded together
Homgenous
Cant see the parts
hetergenous
Can see parts
Chemical Properties
How a substance reacts with other substances
Example of chemical properties
Flammable, Corrosive, Explosive, Ph
Physical Properties
Characteristics of a substance
example of physical properties
Colour, boiling point, Melting point, Solubility
Chemical Families
Groups of elements on the Periodic
Table
Binary ionic
Metal with non metal. they transfer electrons
Molecular Compound
Non metal with Non metal. They share electrons
Polyatomic Ion
Metal with a Polyatomic Ion. They transfer electrons
Acids (OH) and Bases (H)
H with nonmetal or negative Polyatomic .they transfer electrons
Whats the first step to naming molecular compounds
Write the name of the first nonmetal, leave it unchanged
Whats the second step to naming molecular compounds
Write the name of the second nonmetal and replace last syllable with “ide”
Whats the rule on Prefixes while naming molecular compounds
First element gets a prefix if its 2 or more. Second element ALWAYS gets a prefix
What is N2O4
DiNitrogen tetroxide
What Is SF6
Sulfur Hexaflouride
Whats the first step to naming Ionic Compounds
Write the name of the metal ( + ion ) leave it unchanged
Whats the second step to naming Ionic Compounds
Write the nonmetal ( - ion ) and replace last syllable with “ide”
What is NaCl
Sodium Chloride
What is MgF
Magnesium Flouride
Whats the first step to naming Transition Metals
Identify the charge on the transition metal by using the charge of the second element
