A mixture that does not filter out, does not settle out but does show a beam of light.

A mixture that does not filter out, does not settle out and does not show a beam of light.

A mixture that usually has the instructions "shake or stir before using".

The only way to distinguish between a solution and collid is with a beam of light. This is called the _?_ effect.

Phase of matter that has no set volume or shape - it's also very compressible.

Phase of matter that has a set volume but no set shape - it's not compressible.

Phase of matter that has a set volume and shape - it's not compressible.

Arrangement of particles in a solid usually consist of an orderly arrangement of particles in a _?_ (two words to describe the shape of the particles).

While boiling takes place throughout the entire liquid, the process of _?_ is when it vaporizes at the surface.

During a phase change (such as solid to liquid, or gas to liquid) there is a change in heat energy but no change in _?_.

At absolute zero, all matter is in the _?_ phase.

Symbol of the element with 11 protons.

Symbol of the element that has an electron structure of 2,8,3.

Horizontal rows on the periodic table in which the elements all have the same number of e- energy levels.

Columns on the Periodic Table in which all the elements (except He) have the same number of valence electrons.

Electrons that inhabit the outter electron energy level are known as _?_ electrons.

The process of separating a mixture by the boiling points of the substances mixed.

The number of protons + the number of neutrons in an atom.

The number of protons in an atom.

By running a ray between charged plates and observing that it was always attacted to the positive plate, J.J. Thomson discovered the _?_ in 1897.

By shooting alpha particles at a thin sheet of gold, Rutherford discoved that the atom is mostly empty space and that protons exist in the central core of the atom called the _?_.

Two or more atoms of the same element with different atomic masses.

Negatively charged particle, discoved by JJ Thomson, found in orbitals (AKA shells) outside the nucleus.

Mass of a proton or neutrons is one AMU which stands for _?_.

The part of the solution that is in the greater amount and does the dissoving is known as the _?_.

The part of the solution that is in the lesser amount and is dissolved is known as the _?_.

The freezing point of any substance is also its _?_ point.

The condensing point of any substance is also its _?_ point.

If you have ice at 0 degrees Celsius and add heat, the ice _?_.

The idea that all matter is made of moving particles and that their motion determines their phases or states.

Water, like all liquids, will boil at a higher temperature if the _?_ is increased.

A substance like dry ice (CO2) goes through _?_ - going directly from a solid to a gas.

A phase chance from a gas to a liquid such as steam turning to liquid water.

The process of a liquid or a gas spreading out and mixing with the surrounding matter is known as _?_.

Two or more elements chemically bonded in a definite ratio.

Over 80 of the elements on the periodic table are _?_ whos properties (with few exceptions) include malleability, conductivity, solids at r.t. and silver in color.

When two LIQUIDS can be mixed with eachother , such as water and alcohol.

When two LIQUIDS will NOT mix with each other, such as water and gasoline.

Mixing two substances causes _?_ changes because the two substances don't form chemical bonds.
