In addition to score 3.0 performance, the student demonstrates in-depth inferences and applications that go beyond what was taught. Students who demonstrate understanding can: Use the periodic table as a model to predict the patterns of behavior of the elements based on the forces between electrically charged particles and the patterns of valence electrons that determine the typical reactivity of an atom Explain the trend in reactivity and electronegativity of atoms down a group and across a period in the periodic table, based on the attractions of valence electrons to the nucleus. Explain the relative sizes of atoms both across a period (row) and down a group in the periodic table based on attractions of valence electrons to the nucleus. Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion and radioactive decay. Students will : Determine how elements compare to each other based on their reactivity. Use the trend in reactivity and electronegativity of atoms down a group and across a period in the periodic table to compare elements. Predict the relative size of both across a period (row) and down a group in the periodic table. 1. Identify the number of protons, neutrons, and electrons in an atom. 2. Describe the types of radioactive decay. Recognize or recall specific vocabulary such as: Fission, fusion, alpha decay, beta decay, gamma decay, electronegativity, reactivity, atomic radii, Student’s performance reflects insufficient progress towards foundational skills and knowledge.
