Periodic Table Part 9: Noble Gases (He, Ne, Ar, Kr, Xe, Rn, Og)

The video tutorial covers Group 18 elements, known as noble gases, highlighting their properties, abundance, extraction methods, reactivity, and applications. Noble gases are generally inert, with filled valence shells, making them stable. Helium, neon, argon, krypton, xenon, radon, and oganesson are discussed, with a focus on their unique characteristics and uses. While helium is abundant in the universe, it is scarce on Earth. Xenon is notable for forming compounds due to its low ionization energy. Applications range from helium in balloons to neon in lights. Health concerns, particularly with radon, are also addressed.

How do the ionization energies of noble gases affect their reactivity?

Discuss the health risks associated with radon exposure.

What is the significance of oganesson in the context of noble gases?
