Before starting this session, you should be familiar with:
- Basic principles of high school chemistry
- Fundamental concepts of the structure of the atom
Prof. Sadoway discusses the periodic table in more detail (Session 2). He explores the relationship between electronic structure, chemical bonding, and crystal structure (Session 4).
After completing this session, you should be able to:
- Classify a substance as an element or a compound.
- Understand the developmental history of the periodic table of elements.
- Identify the symbols and number of electrons for an element.
- Classify an element as a metal, semimetal or a nonmetal.
- Explain which sets of elements are in the same period.
- Calculate the molecular mass of a compound.
- Calculate the number of moles in a substance.
- Define a homogenous mixture and a heterogeneous mixture.

Periodic Table and Table of Constants
This lecture is an introduction to the class.
Professor Sadoway begins with important information about the course objectives, organization, and expectations, and proceeds to introduce the subject of solid state chemistry. 3.091 integrates thorough coverage of the principles of chemistry with various applications to engineering systems. The thesis of 3.091 is that electronic structure holds the key to understanding the world around us.
The lecture continues with a survey of the historical foundations of chemistry:
- The origins of chemistry in ancient Egypt and Greece
- The development of increasingly refined classification schemes (taxonomy and nomenclature) throughout the 18th and 19th centuries
- The evolution of atomic theory
- The origins and development of the periodic table of elements
