Elijah, David, and Kai are studying nuclear physics. They come across some symbols in their textbook. Elijah thinks they represent an alpha particle. What do you think these symbols represent?

Olivia, Grace, and Samuel are studying isotopes in their chemistry class. They are given three isotopes of the same element. How are these isotopes different from each other?

During a science project, Harper and Benjamin were discussing a nuclear equation. What type of nuclear equation were they discussing?

During a science class, Samuel, Evelyn, and Liam were discussing alpha decay. They wondered what happens to the atomic number during this process. Can you help them?

Aria is studying the decay of the technetium-99 isotope, which has a half-life of 6.0 hours. If she injects 100.0 mg of technetium-99 into a sample, how much of the isotope will remain after 18 hours?

Rohan is studying nuclear reactions and comes across the following equation that needs to be balanced:
¹⁴₆C --> ⁰_-1e + ________

Evelyn is studying nuclear reactions and comes across a decay process. She needs to complete the nuclear equation and determine the type of decay that is occurring in this reaction. What type of decay is it?

Arjun is a scientist working with radioactive materials. He recently obtained a fresh sample of Barium-122 weighing 80g. This particular isotope has a half-life of 2 minutes. Unfortunately, it takes Arjun 10 minutes to set up his experiment. Noah and Michael are curious to know how much Barium-122 will be left when Arjun finally begins his experiment?

Emma, William, and James are studying about radioactive elements in their science class. Their teacher explained that when an element is radioactive, it means what?

Sophia, Rohan, and Abigail are studying nuclear reactions. They come across the following equation: ⁹₄Be  +  ¹₁H →  _____  +  ⁴₂He. They are trying to figure out the missing isotope that will balance this equation. Can you help them?

Zoe, Daniel, and Anika are studying nuclear chemistry. They come across a problem where Thorium-234 undergoes a beta decay. They are curious to know, what element will be left in its place?
