    • When analysing markets, a range of assumptions are made about the rationality of economic agents involved in the transactions
    • The Wealth of Nations was written
      1776
    • Rational
      (in classical economic theory) economic agents are able to consider the outcome of their choices and recognise the net benefits of each one
    • Producers act rationally by
      Selling goods/services in a way that maximises their profits
    • Workers act rationally by
      Balancing welfare at work with consideration of both pay and benefits
    • Governments act rationally by
      Placing the interests of the people they serve first in order to maximise their welfare
    • Rationality in classical economic theory is a flawed assumption as people usually don't act rationally
    • If you add up marginal utility for each unit you get total utility
    • This module was designed and written with you in mind. It is here to help you master the nature of Chemistry
    • The scope of this module permits it to be used in many different learning situations
    • The language used recognizes the diverse vocabulary level of students
    • The lessons are arranged to follow the standard sequence of the course
    • The module is divided into three lessons
      • Lesson 1 - Atomic Structure
      • Lesson 2 - Chemical and Structural Formulas
      • Lesson 3 - Chemical Nomenclature
    • An atom has a mass number of 23 and atomic number 11
    • Mass number
      The number of protons and neutrons in the nucleus of an atom
    • Atomic number
