Q&A for How to Write a Noble Gas Configuration for Atoms of an Element

The noble gas notation for lead is [Xe]6s2 4f14 5d10 6P2.

You would use the noble gas before it. The noble gas for Neon (Ne) is [He] 2s2 2p6.

Any element in column 16. They also have eight valence electrons, so they don't need to gain or lose electrons.

The combining power, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. Valence diagrams of a compound represent the connectivity of the elements, with lines drawn between two elements, sometimes called bonds, representing a saturated valency for each element.

Noble gas notations serve as a starting base in which to write e- configs. For example, in iron, fe, we can write e- config based on the number of protons it contains.
