Question: 1. How are electrons excited in this lab? What does it mean when electrons are excited? 2. In your own words, why do different elements

1. How are electrons "excited" in this lab? What does it mean when electrons are "excited"?

2. In your own words, why do different elements give off different colours when heated? 3. Student A thinks that all neon lights, even those with different colours, contain just neon. Student B thinks that, despite their name, different coloured neon lights must contain different elements. State who you think is correct and explain your choice. Identifies who is correct and provides reasoning. Who is correct?Brief explanation

4. Explain what you think would happen if the wooden splints used in this lab became contaminated? Correctly identifies a reasonable sources Provides an appropriate explanation.

5. Even though all elements give off unique colours when heated, it is impossible to identify all elements with the naked eye by only doing flame tests. Why is this the case?
