STAAR Readiness Standard: 8th Grade Science 8:5 B Name: Date: Objective: After watching the BrainPOP movie about Chemical Bonds, students will describe the structure of an atom and determine and elements identity. 1. Atom- The atom consists of a central, positively charged core, the nucleus, and negatively charged particles called electrons that are found in orbits around the nucleus. 2. Electron- A subatomic particle with a negative electric charge. 3. Proton- A Subatomic particle with the symbol p or p+ and a positive electric charge. 4. Neutron- A subatomic Hadron particle which has the symbol n or n0. Has no net electric charge and a mass slightly larger than that of a proton. 5. Nucleus- A membrane enclosed organelle found in Eukaryotic cells. It contains most of the cell’s genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes. 6. Random- Made, done happening ,or chosen without method or conscious decision. 7. Spherical- A coordinate system for three dimensional space where the position of a point is specified by three numbers: the radial difference of that point from a fixed origin. 8. Ion- An ion is an Atom or molecule in which the total number or electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge. 9. Edible- Able to eat. Name: Date: Objective: After watching the BrainPOP movie about Chemical Bonds, students will describe the structure of an atom and determine and elements identity. 10. Flammable- Easily set on fire. Name: Date: Objective: After watching the BrainPOP movie about Chemical Bonds, students will describe the structure of an atom and determine and elements identity. Directions: Identify how the following atoms stick together by placing the key term beside the correct image.
