Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration.
They are all members of the noble gas group (group 18).
The Noble Gases, formerly known as the inert gases consist of: Helium- He Neon- Ne Argon- Ar Krypton- Kr Xenon- Xe Radon- Ra
nitrogen will get noble gas configuration by adding three more electrons.
Group 8A, the noble gases because they have high electron affinity.
All noble gases or group 18 elements.
All halogens or group 17 elements.
They are all members of the noble gas group (group 18).
Group 18
The noble Gases, He, Ne, Ar, Kr, Xe, Rn.... filled valence electrons
group 13 or IIIA
Elements with similar electron configurations are placed in the same group.
The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.
The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.
The group of elements that have a stable electron configuration are the noble gases.
7A
The Noble Gases, formerly known as the inert gases consist of: Helium- He Neon- Ne Argon- Ar Krypton- Kr Xenon- Xe Radon- Ra
neon, argon, krypton, xenon, and radon. This is because the last number in each of these element's electron configurations is 8.
