Key Ideas: Chemistry 3.0 - 3.4 Mind Map
Atoms
Compounts
Ionic Compounds
Simple Ionic Compound
Give and take electrons between single elements and bond like NaCl
Complex Ionic Compounds
Multivalent
Transitional metals have multiple charges they can form, so their name contain roman numerals to identify which charge they have.
Polyatomic
Multiple elements form an ion which acts as a single particle.
The Zero-Sum Rule: The total charge of bonded ions must add up to 0.
Covalent Compounds
Diatomic Molecules
Elements that are always present as two atoms contently bonded in nature. Almost always exist in pairs
Simple Covalent Bonds
Regular covalent bonds where electrons are shared among non-metals
Properties and Changes
Physical
Properties
Physical Characteristics. Ex: color, texture, density, smell, solubility, taste, melting point
Changes
Changes that don't create new substances not change the chemical properties.
Chemical
Properties
The behavior of the substance. Ex: Flammability, bleaching ability, acids & base reactions, corrosion
Changes
Create new substances
Evidences
New Colour
bubbles
precipitate
energy produced
irreversible changes
Chemical Reactions
Parts of the Chemical Reaction: Reactants, Products, arrow (yield)
Plus sign, states of matter
Word Equation
Chemical Equation
Balanced
Conservation of Mass
Number of atoms on the either side of equation must equal to one another
Skeleton
Not Balanced
Types of Chemical Reactions
Synthesis
Decomposition
Single displacement
Double displacement
Combustion
Hydrocarnons
Complete
Produces CO2 and H2O
(Non-toxic)
Inconplete
Produce other toxic materials as well such as solid C or CO gas
Other Substances
Other substances produce oxide and energy
Hydrogen: Produce water and energy
