Course Overview

Introduction to GOB Chemistry

This course is the first in a three-quarter chemistry sequence designed for nursing and allied health science students. It covers foundational topics in inorganic chemistry and introduces essential concepts in atomic and molecular structure, chemical bonds, stoichiometry, gases and equilibrium, solution chemistry, and nuclear chemistry.

• Course Format: 5-credit lab science course with asynchronous online lectures and 4 hours of laboratory activities per week.

• Prerequisite: Basic algebra knowledge; Math 94 is highly beneficial.

• Required Materials: General, Organic, and Biological Chemistry (8th Edition) by McMurry et al., and Mastering Chemistry Access Code.

Main Topics

Atomic Theory and Composition of Atoms

Understanding the structure of atoms is fundamental to chemistry. This topic covers the basic assumptions of atomic theory and the composition of atoms, including subatomic particles and electronic configuration.

• Atomic Theory: Atoms are the smallest units of matter, composed of protons, neutrons, and electrons.

• Electronic Configuration: The arrangement of electrons in an atom determines its chemical properties.

• Example: The electronic configuration of sodium (Na):

The Periodic Table and Element Classification

The periodic table organizes elements based on atomic number and recurring chemical properties. This topic explains how elements are arranged and classified.

• Periodic Law: Properties of elements repeat periodically when arranged by increasing atomic number.

• Groups and Periods: Vertical columns are groups (families); horizontal rows are periods.

• Example: Alkali metals (Group 1) are highly reactive and have one valence electron.

Chemical Bonding: Ionic and Covalent Bonds

Chemical bonds form when atoms share or transfer electrons. This topic distinguishes between ionic and covalent bonds and discusses their properties.

• Ionic Bonds: Formed by the transfer of electrons from one atom to another, resulting in oppositely charged ions.

• Covalent Bonds: Formed by the sharing of electrons between atoms.

• General Formula: (ionic bond)

• Example: Water () is a covalent compound.

Stoichiometry and Chemical Reactions

Stoichiometry involves quantitative relationships in chemical reactions. This topic covers balancing chemical equations and calculating reactant/product amounts.

• Balancing Equations: Ensures the same number of atoms of each element on both sides of the equation.

• Stoichiometric Calculations: Use mole ratios to determine quantities.

• General Equation:

• Example:

Gases and Equilibrium

This topic explores the properties of gases and the concept of chemical equilibrium, where the rates of forward and reverse reactions are equal.

• Gas Laws: Describe the behavior of gases (e.g., Boyle's Law, Charles's Law).

• Equilibrium:

• Example:

Solution Chemistry

Solution chemistry focuses on the properties and behavior of solutions, including precipitation, acid-base neutralization, and redox reactions.

• Precipitation: Formation of an insoluble solid from a solution.

• Acid-Base Neutralization:

• Redox Reactions: Involve the transfer of electrons between species.

• Example: (redox reaction)

Nuclear Chemistry

Nuclear chemistry studies changes in atomic nuclei, including radioactive decay and nuclear reactions.

• Radioactive Decay: Spontaneous breakdown of unstable nuclei.

• Types of Radiation: Alpha (), beta (), and gamma () radiation.

• Example: (beta decay)

Laboratory Skills and Scientific Method

Laboratory Exercises and Reporting

Laboratory work is essential for developing practical skills in chemistry. Students perform experiments, record observations, analyze data, and present results in written form.

• Scientific Method: Systematic approach to experimentation and analysis.

• Lab Reports: Include objectives, procedures, results, and conclusions.

• Example: Determining the concentration of an unknown solution using titration.
