Been awhile since Chem 1? Let’s cover some of the essentials from general chemistry that you’ll need for this course. 

Recap of Protons and Neutrons

Concept #1: The difference between atomic numbers and atomic mass.

  • Atomic Number: Number of protons in the atom.
  • Atomic Mass: Total number of protons and neutrons in the atom. 
  • Isotopes: Atoms that have the same atomic number but differing atomic mass.

Example #1: Understanding the hydrogen isotopes. 

Recap of Electrons

Concept #2: Shells, orbitals and types of ions  

  • Shell: Region of space that electrons orbit around the nucleus in.
  • Orbital: Region of space within a shell with exactly enough space for two electrons. 
  • Ion: An atom that has an unequal number of electrons and protons.  

Example #2: Understanding the hydrogen ions. 

The Three Principles of Electron Configuration

Concept #3: 3 rules about orbitals you need to know.  

Practice: PRACTICE: Determine the number of protons, neutrons and electrons in the following atoms.
