Why Lesson Planet?
An online resource, this activity has your chemistry learners complete four data tables with information about atoms and chemical bonds. The first table addresses atomic number and mass, as well as numbers of protons, neutrons, and electrons. Table two examines the number of atoms in a chemical formula. Ions are surveyed with a third table in order to prepare learners to understand covalent bonding. Finally, the properties of isotopes are dealt with. Thorough explanations are provided before each chart.
