==================================================

Question: What is a Mixture?

Answer: TWO OR MORE substances combined chemically (Homogeneous OR Heterogeneous)

==================================================

Question: What is a Homogeneous Mixture?

Answer: Same throughout, evenly mixed (solution).

==================================================

Question: What is a Heterogeneous Mixture?

==================================================

Question: What is a Compound?

Answer: A chemical combination.

==================================================

Question: What is a Mixture?

Answer: A Physical Combination.

==================================================

Question: What is Physical Change?

Answer: Change in size, shape, color, or state (solid, liquid, or gas) but maintains its same chemical characteristics.

==================================================

Question: What is a Chemical Change?

Answer: Change of a substance to a new substance with a DIFFERENT chemical mak eup.

==================================================

Question: What is a Physical Property?

Answer: A characteristic you can observe without changing the chemical make up.

==================================================

Question: What is a Chemical Property?

Answer: Describes it a material can undergo a specific chemical change.

==================================================

Question: What is The Law of Conservation of Mass?

Answer: The Mass of all substances before a chemical change equalls the mass of all substances after the change.

==================================================

Question: What is the Atomic Number of an Element?

Answer: Tells you how many Protons are in one atom (Organized Numerically on the Periodic Table by Atomic Number).

==================================================

Question: What is a Proton?

Answer: Positively charged particles in an atoms nucleus, gives an element its identity, has a mass amount of 1 amu.

==================================================

Question: What is a Neutron?

Answer: Neutral particles in an atoms nucleus, have a mass of 1 amu.

==================================================

Question: What is an Electron?

Answer: Negatively charged particles, orbit around the nucleus in energy levels, have almost no mass.

==================================================

Question: What is the Atomic Mass of an Element?

Answer: The average mass of all the isotopes of that element.

==================================================

Question: What is the Mass Number of an Element?

Answer: Atomic mass rounded to the whole number (EQUAL to the total amount of Protons and Neutrons in one Atom).

==================================================

Question: Mass Number - Atomic Number = ?

Answer: Number of Neutrons

==================================================

Question: What are the 3 States (Sometimes 4) of Matter?

Answer: Solid, Liquid, Gas, and Plasma (Sometimes)

==================================================

Question: What is a Solid?

Answer: Has definite shape and Volume.

==================================================

Question: What is a Liquid?

Answer: No definite shape BUT has definite Volume (Water changing glasses = Same Volume, but takes different shapes)

==================================================

Question: What is a Gas?

Answer: No definite shape ad No definite Volume.

==================================================

Question: What is Plasma?

Answer: A Gas-like mixture of charged particles that exists at very high temperatures.

==================================================

Question: What is the change of a Solid to a Liquid?

Answer: Melting

==================================================

Question: What is the change of a Liquid to a Solid?

Answer: Freezing or Solidification

==================================================

Question: What is the change of a Liquid to a Gas?

Answer: Evaporation

==================================================

Question: What is the change of a Gas to Liquid?

Answer: Condensation

==================================================

Question: What is the change of a Solid to a Gas?

Answer: Sublimation

==================================================

Question: What is the change of a Gas to a Solid?

Answer: Deposition

==================================================

Question: What is an Isotope?

Answer: An atom of the same element that has a Different Number of Neutrons therefore a Different Mass.
