The grade 11 chemistry class continues to develop their mathematical and experimental/Inquiry skills through lab investigations and practical work. This is essential in their preparation for the 10 Hour long Internal Assessment where they will be required to design an experiment in a topic of their interest and analyze data.
This week’s focus was how we can model the energy states of electrons in atoms. The students did a series of experiments on atomic emission that helped them identify the presence of some metals using flame tests.
Flame testing is an analytical technique where a sample is placed in a flame, and the characteristic flame color is used to identify the substance. Each element has a characteristic light emission when placed into a flame, meaning each element produces a unique color.
