States of Matter
The 4 States of Matter are
Going from a LIQUID to a SOLID
Freezing
Elements and Compounds are examples of
Pure Substances
Ni - Nickle , B- Boron, Li- Lithium are all examples of
Elements
Chemical Change
is made up of atoms and molecules that acts as tiny particles
Matter
Going from a GAS to a LIQUID
Condensation
A combination of two or more substances that are physically combined
Mixtures
Protons P+ and Neutrons N0 are located in the
Center or Nucleus
Solubility is an example of an
Physical Change
Has an indefinite shape and a definite volume
Liquid
Going from a SOLID to a GAS
Sublimation
A mixture where substances are evenly distributed through the solution and is uniform. Particles ARE NOT easily visible
Homogenous Mixture
Electrons are located on the
Energy Levels, Shells, or Electronic Cloud
Physcial Changes/Properties
Particles are tightly packed together and vibrate in place
Solid
Going from a LIQUID to a GAS
Evaporation or Vaporization
A single kind of matter that cannot be separated into other kinds of matter by any physical means
Pure Substance
Electrons that are located on the outer most shell and are used in the Lewis Dot Structure
Valence Electrons
Occurs when one or more substances change into entirely new substances with different properties
Chemical Change
IF's become stronger as molecules come together
Intermolecular Forces
Water starts to boil at 100 degrees Celsius
Boiling Point
is a mixture that DOES NOT have a uniform mixture , can easily spot and separate products from it
Heterogenous Mixture
H2O is an example of a
Compound
Adding sugar to a flask and add a drop of sulfuric acid
Heat is given off and a black, sticky substance is produced
Chemical Change
