Concept explainers
Interpretation:
The maximum number of valence electrons that a representative element/noble gas can posses and which group of elements possess this maximum number of valence electrons has to be idenified.
Concept Introduction:
Electronic configuration of an atom is a shorthand method of writing the location of electrons in the atom. The electrons present in the outermost shell of the atom are known as valence electrons. The valence electron configuration of the noble gases is considered the most stable of all valence electron configurations. Except Helium, all other noble gases possess

- 1. Hydrogen is a Group I element and each hydrogen will contribute I valence electron. Carbon is a Group (Roman numeral) element and each carbon will contribute ___ (number) electrons. Every oxygen atom in a compound will contribute valence electrons. Chloromethane has the molecular formula . Its skeleton is and the number of valence electrons may be determined as follows. There are three hydrogen atoms, each of which contributes 1 valence electron; the single carbon contributes 4 electrons; and the single chlorine atom contributes 7 electrons, making a total of 14 .
