The opposing team then decides if the model is correct. If it is deemed right, then the next element is presented. If it is incorrect, both teams must continue working as before. Continue the activity with other elements from the periodic table to offer students an opportunity to practice a variety of electron configurations. This will also allow other students to serve as team leaders.
Extensions Integrate the use of ions into the above exercise.
Students pick an element to research using web and library sources. Students produce a power point presentation on their element. Students with Special Needs Students who may not be able to move readily about the room could remain stationary and provide an anchor point for the atomic models. They can also direct construction of their team's model. Click here for further information on laboratories with students with special needs.
