Laboratory Task: due towards the end of lab

You will operate groups for today's research laboratory. Work on the side benches rather than in the blow up hoods. You will need one bag (approx. 95 chips) of each and every color intended for today's lab. Using the coloured chips, create a model to fill in the table and write a well-balanced nuclear equation for each response below. The model need to clearly display a nucleus and an electron cover and you will need to have a key pertaining to the color assignment of the subatomic particles. Basically answering the question(s) without building the model(s) will mean a report of zero for invisalign portion of this assignment. You must also fill in every blank effectively. Hint: the banker inside the group can easily " generate change”, i. e. exchange a wasserstoffion (positiv) (fachsprachlich) and a β compound for a ungeladenes nukleon. 1 . Two atoms of helium-3 react to form helium-4 and ______________________. This is a good example of a _______________________ reaction. Prior to reaction Protons Neutrons Bad particals Equation: After reaction Transform
