Elements And Atoms 3/18/17

Science Notes and Projects
Summary: Atoms are what make up literally everything. Atoms are made up of Protons, Neutrons and Electrons. The middle of the atom is the Nucleus. The Nucleus is made up of Protons and Neutrons. The Electron is flying around the Nucleus. Electron's have a Negative Charge, Protons have a Positive charge and the Neutrons have a neutral charge. The Protons are what determine/identify what type of atom it is. Elements are made up of only one type of atom. And ALL Elements are found on the periodic table. If its not on the periodic table then its not an Element. Density is how much stuff is in a given space. Mass divided by Volume is the formula to find the density of something. And Volume is the amount of space something takes up. To find volume you must do length times width times height.

SP3: Planning and carrying out investigations: To figure out more about density,volume, and mass we did an experiment in which we had giant tub of water. Then we had different types materials that all had different densities, mass and volume. Some of the materials sunk because they had more density and mass while some didnt because the had less volume and mass. We also tried to use aluminum foil we filed it to the size of the bin of water and put it in. It floated. But we folded it into a little square to make it more dense and then it sunk.

XCC: Cause And Effect: The amount of protons an atom has is what identify what type of atom it is.  If your atom has a negative charge it is called a cation. This happens when electrons get added giving the atom an negative charge. If electrons are lost then the atom has a positive charge which makes it a anion. Cause and effect is very key in the atoms. So if a atom is positive its a anion. If it has a negative charge then its a cation.
