Noble gases are those which are colorless, odorless, tasteless, and non-flammable. Their name comes from the fact that they were initially believed to never bond with other atoms which was later disproved.
The element mercury (Hg, atomic number 80) has the electron configuration [Xe] 4f14 5d10 6s2
An atom in a ground state with 8 valence electrons is likely to be an oxygen atom. Oxygen has 6 electrons in the outermost shell, also known as the valence shell, along with 2 electrons in the inner shell. This configuration allows oxygen to easily form chemical bonds with other atoms to achieve a more stable electron configuration.
Yes, they have stable electron configuration i.e, their outer most shell has all its valence electrons filled.Some famous noble gases areHelium (He)Neon (Ne),Argon (Ar),Krypton (Kr),Xenon (Xe),and the radioactive Radon (Rn).
