Narrator: In plain English, neptunium is a man-made element that comes after uranium.
Narrator: It is named after the planet Neptune, which lies beyond Uranus.
Narrator: "Neptunium-237" describes its longest-lived isotope, found in nuclear waste.
Narrator: It differs from uranium because neptunium comes after it and is almost entirely man-made.
Narrator: "Transuranium element" is a second pattern, meaning any element heavier than uranium.
Narrator: Nuclear power, physics and radiation detection rely on neptunium.
Narrator: So remember: neptunium is the first element beyond uranium, named after Neptune.
Speaker A: What is neptunium?
Speaker B: The element after uranium! NEPTUNIUM is named after the planet Neptune.

Prompt: Explain how uranium, neptunium and plutonium were named after planets.
Speaker A: How about waste?
Speaker B: Ask the model to summarise:
Prompt: Summarise why neptunium matters in long term nuclear waste storage.
Speaker A: Could it help with data?
Speaker B: Yes, you can frame cards:
Prompt: Add neptunium to the element table with symbol Np and atomic number 93.
Speaker A: One more?
Speaker B: For a timeline, try this:
