Transcript of Elements, Compounds, Mixtures and Matter

Esther, Neha, Nicholas, Shane Elements, Compounds, Mixtures and Matter What is Matter? Periodic Table Elements Mixtures Compounds Bibliography Matter is anything that has mass and takes up space. All matter is made up of elements like oxygen, it is an element which means it is matter. Also, gold is also an element and matter. Even Your phones are made of matter. There are five states of matter, solid, liquid, gas, plasma, and Bose-Einstein Condensate(BEC) , but we will only talk about solids, liquids, and gases. A solid has definite shape and volume. Its molecules are compacted. A liquid has no definite shape, but it does have definite volume. Some examples of a solid is a lego and a iPad. The molecules in a liquid slip and slide past each other. Therefore the liquid flows freely and can take the shape of it’s container. One example of a liquid is water in a bottle. A gas has no definite shape but it has volume. it’s molecules bounce around randomly and they equally take up all the space in the container or room it is in. One example for a gas is the oxygen floating around in the room. There are five types of elements. Chemical elements, Electrical elements, Heating elements, Orbital elements, and Weather.We'll be talking about Chemical elements only. Chemical element is a pure chemical substance and is made up of one atom. Chemical elements are listed on the Periodic Table. The 3 types of chemical elements are metals, nonmetals, and metalloids. Examples of elements are: Oxygen, Gold, Silver, Copper, etc. Compounds-A compound is a substance that is made up of 2 or more elements that is connected by a chemical bound.Example: salt (Sodium chloride) is made up of Na and Cl or NaCl, water (Hydrogen + Oxygen) is made of H2 and O or H2O. Mixtures- A mixture is a chemical system made up of 2 or more different substances. Mixtures are a product of mechanical blending. It can be a mixing of elements and compounds. Some mixtures can be separated into their components by physical changes. Examples: concrete and salt water. http://en.wikipedia.org/wiki/Chemical_element

They all have a symbol and an atomic number so you can find them easily. Also, the atomic number of an element shows the number of protons the element has like the atomic number for Lithium is 3 so it has 3 protons. The grid is 18x7 grid.There is 118 elements in the periodic table.There are 18 groups and seven periods. The periodic table of the elements is the collection of all the known elements in the world. The are sorted into periods and groups . Each element show atomic number ,atomic mass,Symbol, and element name. THE END!
