differentiate BTW oxidation number and valency.
Answers
All compounds are made of atoms of different elements. These atoms are combined in different ratios according to the number of available free orbitals they have or the number of electrons that a particular atom can release. Valency and oxidation state are two terms used to explain the reasons for these different combinations of atoms. The main difference between valency and oxidation state is that valency is the number of electrons present in the outermost shell of an atom of a particular element whereas oxidation state is the number of electrons that an element in a particular compound has lost or gained.
Valency can be defined as the number of electrons present in the outermost shell of a particular element. Valency determines the maximum number of bonds that a particular atom can have. The elements in the periodic table are grouped according to the number of valence electrons (electrons in the outermost orbitals) an atom can have when it is in the neutral and gaseous state. The following table will explain this.
Answer:
Valency is the maximum no. of electrons which an atom can lose or gain while oxidation no. is the actual no. of electrons which the element lose or gain to form a molecule
. Valency is the property of an isolated atom whileoxidation state is calculated for an atom is present in a molecule i.e, in a bonded state
