Neptunium is a special metal that belongs to a group called actinides. It was discovered in 1940 by scientists Edwin McMillan and Philip H. Abelson at the University of California, Berkeley. Neptunium is really cool because it glows in the dark! 🟣
It is named after the planet Neptune, which is the eighth planet from the Sun in our solar system. Neptunium is rare on Earth but can be found in trace amounts. You will mostly find it in nuclear reactors, and it can be radioactive, meaning it can release energy as small particles! ⚛
