Radium is a shiny, silvery-white metal. 🌈
It is very soft, which means it can be easily shaped. Radium is radioactive, which means it can release energy in the form of radiation! It has a very unique
atomic number, 88. That’s pretty cool! 😎
Radium can glow due to its radioactivity, and it was used in glow-in-the-dark paint. However, radium is very heavy; it is nearly 70 times heavier than aluminum! Its melting point is around 700°C (1,292°F), making it very resistant to heat. How awesome is that? 🔥
