Welcome to Dr. Deratzou's Radnor High School
Home Page.
Chemistry is an exciting science and we will be doing a lot of work in our Chemistry classes. Chemistry is the study of chemicals and chemical reactions.  We will be studying atoms, molecules, naming and writing formulas, periodic trends, chemical bonding, chemical reactions, stoichiometry, and gases, to name a few topics. 
Please check out the Schoology Page for specific information about the courses that I teach.

  • Radnor High School is participating in a district initiative to enhance communication with students and parents through Schoology, an online learning management system, that allows users to safely and securely share academic content. All RHS teachers are using the system with students this school year. To increase efficiency of classroom management, teachers will not be updating their webpages as frequently. Directions for parent access to Schoology is available. Home Access Center (HAC) will continue to serve as the place for parents to view current grades.
