Radiometric dating worksheet answer key
A number of interactive and visual resources will be used to enrich the learning experience.This year, students will complete a detailed creative writing assignment as the summative assessment for the unit. Unit 9: Nuclear Chemistry In this brief unit, we will consider the factors that make for unstable nuclei--and what then happens to those radioisotopes.We will learn to balance nuclear equations, solve radioactive dating problems involving half-lives, and calculate binding energies.We will also consider medical applications of radioisotopes and the effects of radiation on human tissue.We will also learn about energy relationships in various situations.Unit 2: Introduction to Atomic Theory and the Periodic Table (Chapter 4) The structure of the atom is a central theme in chemistry.Quantitative aspects of chemical concepts are emphasized throughout the course.
Attractions between molecules will also be considered.In this unit, we will trace the development of an atomic theory of matter and changes to the theory as new experiments result in further insights.We will also discuss the development of the periodic table and use the periodic table to discuss trends in elemental properties.We clean the windows with ammonia solutions and use Drano to unclog the sink--everyday sources of bases. This occurs when atoms gain electrons ("reduction") or lose electrons ("oxidation"). Additionally, these reactions can be harnessed to create batteries!We will use our knowledge of oxidation-reduction processes (or "redox") to predict the voltage produced in electrochemical cells. We start by exploring appropriate use of data in science, using significant figures for both measurements and calculations, through a series of hands-on activities.
This will include exceptional electron configurations, typical ions formed by the elements, and Lewis dot structures to represent those most important electrons, the valence electrons.
