Matter what is it?Matter is everything around you. Matter is

anything that are made up of atoms and molecules. Matter is anything that has mass to fill up an object of what it is talking up. Matter is also related to the light and electromagnetic radiation. Even though matter can be found all over the universe you would find it in three different forms and they would be solid liquid and gas.

States of matter what are they? Solid-Solids are usually hard because their

molecules have been packed together. Gas-Gas is everywhere. There is something

called the atmosphere. That's a big layer of gas that surrounds the Earth. Molecules move really fast

Liquid-Water is a liquid. Your blood is a liquid. Liquids are an in-between state of matter. They can be found in between the solid and gas states. Molecules move fast but slower then a gas.

Five examples for each state of mattersolid-ice, brick, rock, book, penLiquid-water,kool-aid,ocean water,tea,lemon

juice gas-Oxygen, Argon, Nitrogen, Acetylen,

Hydrogen

Physical and chemical?Chemical change is any change that results

in the formation of new chemical substances. At the molecular level, chemical change involves making or breaking of bonds between atoms. These changes are chemical(next slide)

VsPhysical change rearranges molecules but

doesn't affect their internal structures. Some examples of physical change are(next slide)

5 ex: of Physical and chemical

Physical: whipping egg whites, Magnetizing a compass needle, dissolving sugar in water ,dicing potatoes

Chemical: baking bread, rusting iron, cooking eggs, milk turning bad, gasoline burning

Physical and chemical properties physical properties are those that can be

observed without changing the identity of the substance. The general properties of matter such as color, density, and hardness, are examples of these.

chemical properties are properties that determine how a substance changes into a completely different substance. Flammability is one way to determine if it is a chemical change

Properties of chemical and chemical Physical-Density, Solubility, Conductivity,

Mass ,VolumeChemical- Mass, density, melting point, latent

heat, conductivity.

Atom what are they?Atom-If you want to build molecules, you will

need elements. Each element is a little bit different from the rest. Those elements are the alphabet to the language of molecules.   An atom is the basic unit of an element. An atom is a form of matter which may not be further broken down using any chemical means. A typical atom consists of protons, neutrons and electrons. Ex: calcium atoms, sodium, chlorine, and sulphur atoms

Gold elementsProtons=79Neutrons=118Electrons=79Classification=metal, solidElements name=goldElement symbol=Au

What is an elementan element is a pure substance that cannot

be broken down into any simpler substances by chemical methods. An element is the simplest kind of matter. Each element retains its own unique properties. For example, each element has its own atomic mass, and the number of protons and electrons for an element always remains the same, although the number of neutrons can be small.

5 examples of an elementsElements-lead, potassium, mercury,

hydrogen, helium, oxygen, carbon, chlorine.

What is a compound?A compound is made up of two or more types

of elements (water and carbon dioxide) that are chemically combined in a set. They cannot be broken down into two or more simpler substances by physical means, only by chemical means. Properties of compounds are different from those of their elements. For example, salt is made up of two elements: chlorine, which is poisonous; and sodium, which reacts explosively with water. 

5 ex: of compoundCompound –water glass sugar salt and plastic

What is a periodic table.The periodic table is a table of the chemical

elements, showing the symbols for the elements, their full names, their atomic numbers and their mass number. It organizes them into groups and periods (columns and rows) based on their structure and properties. It is called "the periodic table" because the horizontal rows are named "periods." 

Substances and mixture?A substance is pure- it can't be broken down

using Chemical processes A mixture can be separated using physical

processes. A mixture is a combination of substances

with. A substance has to be separated by using chemical needs and a mixture has to be separated by physical needs.

Heterogeneous and homogenous?Heterogeneous-A Heterogeneous mix is

unevenly mixed because you could see what ever you have mixed together like iron and sand you could see the iron and sand

Homogenous-A Homogenous mixture is evenly mixed because you can not see what you just mixed like sugar in water because you can see the sugar in the water but you can taste it.

Heterogeneous and homogenous 5 examplesHeterogeneous-sand with water, iron with

water, iron and sand, paper with water, Homogenous-salt with water, sugar with

water, tea, lemon juice.

Solutions what are they?Solutions- A solution is a mixture of one

substance dissolved in another so the properties are the same throughout. A solution is composed of a solute and the solvent.

Solvent-substances that dissolves the soluteSolute –substance the dissloved

Solutions 5 examplesSolvent-water, lemon juice, co2 gas.Solute-powder, salt, tea powder, kool-aid

powder.Solution-Lemonade, soda pop, kool-aid,

What is solubilitySolubility-Solubility is the maximum amount

of a solute which will dissolve in a given amount of solvent at a fixed temperature.
