It has 4 electrons in its valence shell with a main valence number of 4. that's plenty extra efficient to apply 'oxidation sort'. Valency of some elements which do not combine with hydrogen then becomes the combining power of the dement with an element whose valency is known. Textbook Solutions 19009. Hence, nitrogen valency is 3, while oxidation numbers can range from -3 to +5. Question Bank Solutions 6882. Expert Answer: Nitrogen has atomic number 7 and it has 2 electrons in K shell , 5 electrons in L shell and needs 3 more electrons to gain noble gas configuration. Join now. The compound in which the metal has higher valency is called ‘-ic’ compound while the compound in which metal has lower valency is called an ‘-ous’ compound. The next orbital holds up to 8 electrons. NH3, for instance, is an example of nitrogen bonding covalently with three hydrogens (which each have one valence electron) to give the nitrogen a full eight electron in its valence shell. rules: The sum of the oxidation numbers is comparable to the chrge on the particle. Electrons will occupy the most stable position first. Follow us for the latest industry news, company updates, and our newest features. C. 3. S o l. let the valency of nitrogen in be x. Nitric oxide no 2 or nitrogen dioxide is a nitrogen compound with valence 4. The words valence and valency have two related meanings in chemistry.

Nitrogen is the lightest member of group 15 of the periodic table, often called the pnictogens. Nitrogen has 2 core electrons and 5 valence electrons. y This is written as H 2 O. y The valency of nitrogen is 3. y Hence, three hydrogen atoms can combine with one nitrogen atom. It is a brown gas produced generally by the reaction of concentrated nitric acid with many metals. Magnesium combines with oxygen forming magnesium oxide MgO Valency of oxygen is two hence valency of magnesium is Two. D. 4. This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other atoms.
