The Deep Dive
Helium is a noble gas that is often celebrated for its lightweight and non-reactive properties. Its atomic number, which is two, is determined by the number of protons in its nucleus. This means that helium atoms have two protons and, typically, they also have two neutrons, which helps to maintain nucleus stability—making helium an essential building block in the universe!
In the real world, helium is not just something used in balloons for parties! It’s essential in applications like cooling superconducting magnets in MRI machines, as well as in cryogenics, aerospace, and even in making fiber optics. Plus, it has a myriad of uses in scientific research, making it a super important element!
