What is the noble gas notation for NA?

The elements that are found in the last column of the periodic table are an important group of elements that are called the noble gases. They are helium, neon, argon, krypton, xenon, and radon….Noble Gas Configurations.

Element Name Sodium
Symbol Na
Atomic Number 11
Noble Gas Electron Configuration [Ne]3s1

How do you find the noble gas notation?

A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of [Ne] for the 1s22s22p6 part of the configuration. Sodium’s noble gas configuration becomes [Ne]3s1.

What is the noble gas notation for nitrogen N?

The noble gas configuration of nitrogen is: [He]2s22p3 .

What is the orbital notation for mercury?

What is the electron configuration of S2 −?

The S2- ion, the simplest sulfur anion and also known as sulfide, has an electron configuration of 1s2 2s2 2p6 3s2 3p6. A neutral atom of sulfur has 16 electrons, but the atom then gains an additional two electrons when it forms an ion, taking the total number of electrons to 18.
