The combining capacity, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of … See more In chemistry, the valence (US spelling) or valency (British spelling) of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules. See more Valence is defined by the IUPAC as: The maximum number of univalent atoms (originally hydrogen or chlorine atoms) that may combine with an atom of the element under consideration, or with a fragment, or for which an atom of this element can be substituted. See more Because of the ambiguity of the term valence, other notations are currently preferred. Beside the system of oxidation states (also called oxidation numbers) as used in Stock nomenclature for coordination compounds, and the lambda notation, as used in the See more • Abegg's rule • Oxidation state See more The etymology of the words valence (plural valences) and valency (plural valencies) traces back to 1425, meaning "extract, preparation", from … See more For elements in the main groups of the periodic table, the valence can vary between 1 and 7. Many elements have a common valence related to their position in the periodic table, and nowadays this is rationalised by the See more Frankland took the view that the valence (he used the term "atomicity") of an element was a single value that corresponded to … See more WebApr 6, 2024 · Hint: The combining capacity of an element will tell you the number of atoms that are bonded to the given atom. Thus, if you count the number of bonds around the central atom, you can determine its combining capacity. Complete answer: The combining capacity of an element is dependent upon the number of electrons needed by an atom …
