Chemistry

• Matter: Anything that occupies space
• What is not matter?

  Anything that does not occupy space, such as feelings.
• Time is an example of..

  non matter.
• Force of Attraction: The force that keeps particles together.
• Thermal Energy: The force that keeps particles separated.
• When FOE overpower TE, the solid state is formed.
• When TE overpowers FOE, liquid or gaseous states are formed.
• When gas is further heated under extreme conditions, plasma forms.
• When particles in the gaseous state go through a process called ionization, plasma is formed.
• Plasma reacts with the charges in our body

  
• Plasma: State of matter consisting of free charged particles.
• Examples of PLASMA

  Lightning, solar wind, aurora, Nascent lightning, nuclear fireball.
• When solids are further cooled, they form a state called the Bose-Einstein Condensate.
• Properties of matter

  Physical, chemical.
• metals form cations
• Tendency of metals to loose e- is called electropositivity
• Non-metals tend to gain electrons
• The tendency of non-metals to gain electrons is called electronegativity
• Metals give e- to nonmetals
• Homogeneous mixtures are mixtures in which the components are uniform in structure or composition. (completely dissolve)
• Heterogenous mixture are mixtures that have different compositions, structures, or properties. (particles do not mix together)
