Bohr Models & Energy Levels
1 Direct Instuction
Using knowledge of atomic numbers, draw simple Bohr Models of several elements. Identify the number of electrons that can be held in each shell.
2 Guided Practice
Have the students complete the pre-gizmo activity. Discuss the answers as a group.
Students will work in small groups to complete the electron configuration Gizmo
3 Independent Practice
Students will answer the following questions and upload their answers to the class Google Drive
Look at the first four shells. What is the relationship between the shell number and the number of subshells it contains? [The number of subshells is equal to the shell number. The fifth, sixth, and seventh shells have room for more subshells, but there are no elements with enough electrons to fill them.]
How many orbitals are there in the s, p, d, and f subshells? Is there a pattern?
How are the s, p, d, and f subshells shown in the periodic table?
Metals form bonds when they lose their outermost electrons. How could losing outer electrons lead to a stable electron configuration
Students will be assigned an element and asked to create an informative prezi presentation about their elements characteristics. They will be required to include an electron configuration of their element.
