A Mixture is a combination of two or more Pure Substances, meaning it has two or more molecules.]]> 2017-03-21 00:57:51 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161359510 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161361243 An element is made of ONLY one type of atom. Example: The element of Iron is made up of only Iron Atoms. A compound contains more than one kind of atom. Example: Water is a compound of Hydrogen and Oxygen. 
A mixture is made up of non-chemically joined substances while a compound is a substance made when two or more elements are chemically joined by the chemical bonds between their atoms.]]> 2017-03-21 01:08:42 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161361243 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161362592 2017-03-21 01:20:46 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161362592 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161368487 Conductivity- to measure the ability to conduct heat, sound, or electricity.
~Example: Metal spoon gets hot after sitting in boiling water through Conductivity.
State of Matter- Solid, Liquid, or Gas.
~Example: A solids molecular structure is tightly packed and in a sort of pattern. A liquid's molecular structure is tightly packed, but has not pattern, allowing the molecules to move and/or flow. A gases molecular structure is not tightly packed and the molecules can move freely. 
Density- the measure of mass per volume, mass/volume.
~Example: Because oil is less dense than water, oil floats on water, the density of water is greater than the density of oil. 
Solubility- to measure the ability to dissolve.
~Example: Salt highly soluble in water. When mixed together, salt dissipates in the water, but it is still there. 
Durability- to measure the ability to withstand wear, pressure, or damage.  *only a measure for solids. 
~Example: Copper is more durable than Aluminium because the molecules inside the copper are packed tighter than than the ones within aluminum, making it more durable.
Malleability- to measure the ability to bend/ shape differently without breaking.  *only a measure for solids. 
~Example: Gold is more malleable than Zinc because Gold can bend and can be shaped in to different shapes more than the extent of Zinc can. You don't usually see Zinc being made into anything, but you see Gold because it is more malleable. 
Ductility- the ability to be put under stress, usually to make wire. *only a measure for solids. 
~Example: Copper is more ductile than concrete because after being put under tensile stress, copper can be made into wire and concrete will become brittle. ]]> 2017-03-21 02:20:43 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161368487 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161368614 Flammability- the ability to burn/ignite causing a fire or combustion.  
~Example: Gasoline is more flammable than water because gasoline contains substances that are reactive to fire while water is neutral and cannot react to fire or com bust.
Reactivity- the ability to react chemically, a state of power or reaction. 
~Example: Sodium is more reactive than Argon because Sodium reacts with water chemically while Argon is non-reactive to any elements or compounds. 
Combustion- the process of burning something, production of heat and light. 
~Example: Burning wood on a campfire gives off light and heat, plus needs oxygen and a fuel to burn. ]]> 2017-03-21 02:22:32 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161368614 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161369546 Common Examples: Wood, Stone, Sand, and Ice.
Solids such as metals can conduct heat, sound, or electricity. Solids are also usually more dense than liquids and gases. Some solids are soluble in different liquids, like salt and water. Not all Solids have the same durability or malleability, some can withstand more pressure while the other can bend easier. It all depends upon the molecular structure of the solid. All solids have a similar molecular structure, the molecules are tightly packed together and in a pattern unique to different solids. ]]> 2017-03-21 02:34:37 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161369546 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161370594 Common Examples: Water, milk, gasoline, and paint. Some liquids can conduct electricity, but most liquids do not conduct electricity, but can conduct heat and sound. Different liquids have different densities, the less dense liquid sitting on another more dense liquid will stay on top because the denser the liquid stays on the bottom. Liquids are soluble in other liquids, but to different extents. Some liquids may dissolve in one liquid, but not another. The molecular structure of all liquids have tightly packed molecules, but not as tight as a solid, and a somewhat unorganized pattern unique to different to liquids.   ]]> 2017-03-21 02:48:14 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161370594 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161372172 Common Examples: Oxygen, Helium, Hydrogen, and Nitrogen. Gases to conduct electricity, but at such a small level, it can't be measured. Electricity requires the movement of electrons, but the electrons in a gas are so disperse, barely a current is made. Different gases have different densities like solids and liquids. You can find the density of a gas by weighing and dividing by the volume of the gas, just like a liquid and solid. Gases, believe it or not are soluble. When gases dissolve, they release heat! The molecular structure of all gases are very similar, the molecules not tightly packed and there is not pattern with the molecules. ]]> 2017-03-21 03:05:41 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161372172 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161374648 The Atomic Theory is the theory that suggests that everything is made up of tiny particles called atoms. It suggest that everything and everyone is made of matter that is made up of atoms.

The Three Parts to the Atomic Theory:
1.) All matter is made of Atoms.
2.) Atoms are invisible and indestructible.
3.) Compounds are formed by a combination of two or more different kinds of atoms]]> 2017-03-21 03:31:33 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161374648 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161375291 An atom is a tiny invisible particle suggested by the Atomic Theory to be what makes up all matter. It is also a measurement for chemical elements.

Structure of an Atom:
Atoms are made up of four basic parts; Protons, Neutrons, Electrons, and a Nucleus. The Nucleus is the center of the atom, Protons are positively charged particles within the Nucleus of the Atom, Electrons are negatively charges particles that surround the Nucleus in paths called orbitals, and Neutrons are neutral particles also found within the Nucleus. ]]> 2017-03-21 03:38:33 UTC https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161375291 20dpeterson1 https://padlet.com/20dpeterson1/mdlkoebwlyex/wish/161729916 Common Examples: Solar Wind given off the Sun, Lightning, and Neon Signs.
A Plasma by definition is a gas of charged particles, The movement of charged particles is what makes and electrical current, so Plasma can conduct electricity. 
When talking about the density about plasma, you measure it electrons/ volume rather than mass/ volume because Plasma is basically a big mass of charged particles. SO, some plasma's are more dense than others based on their electron count. The molecular structure of a plasma is very similar to a gas, the molecules are more spread out and no pattern is shown with the molecule, but the significant difference is the number of charged particles compared to gases. Plasma's have more charged particles than any gas on Earth.
