Ans: The combining capacity of an atom is called its valency. Actually it can be defined as the number of electrons that an atom may lose (or) gain during a chemical reaction (or) the number of electrons shared. Ex: In water molecule H?O (H - O -- H) Valency of Hydrogen is ‘ 1 ‘ (as it combines with...

Ans: The combining capacity of an atom is called its valency. Actually it can be defined as the number of electrons that an atom may lose (or) gain during a chemical reaction (or) the number of electrons shared. Ex: In water molecule H?O (H - O – H) Valency of Hydrogen is ‘ 1 ‘ (as it combines with Oxygen atom by one single bond) and valence electrons in Hydrogen = 1 Valency of Oxygen is ‘2’ (as it combines with two Hydrogen atoms by two bonds), but valence electrons in oxygen = 6 The numbers of electrons in outermost shell (or) valency shell of an atom are called valency electrons. Based on valency electrons the group number of an atom can be found. Ex: Number of valence electrons in chlorine are 7 so it belongs to VIIA - group, but its valency is 1. So, it is to be understood that some times valency is equal to valence electrons, but not all the time. read less

Valency is the number of electrons required to be accepted/lose/shared by the atom of an element in order to complete its outer shell octet. On the other hand valence electrons is the number of electrons present in the outermost shell of the atom of an element.

Valence is the number of chemical bonds an atom can form. example: hydrogen has a valence of one whereas Valence electrons are electrons that can participate in chemical bonds with other atoms.

valency can be referred as the combining capacity of an atom to form a molecule or when it is forming a chemical compound.The valence of hydrogen atom is 1. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of two.Valence diagrams of a compound...

In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of two.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. Valence electrons is the no:of electrons available at the valence shell so that it can use these atoms to combine with other molecules to form a compound or with same atom to form a molecule. read less
