Valency depends on the number of electrons in the outer shell available for bonding. 9 Are noble gases valency zero due to stability? Yes, noble gases have a valency of zero as their outer shells are full, making them stable. 9 Can valency predict an element's reactivity? Yes, elements ...
Valency is the combining capacity of the elements to form compounds. During the formation of the molecules of the compounds, atoms combine in certain fixed proportions. Visit BYJUS to learn more about it.

the greater the distance of the electrons from the nucleus. Atoms try to achieve a stable state similar to that of the noble gases or the inert elements in their outermost orbit by accepting or donating electrons. This property is called the atom's valency. ...
Electrons exist in orbits around an atomic nucleus. The higher the orbit number, the greater the distance of the electrons from the nucleus. Atoms try to achieve a stable state similar to that of the noble gases or the inert elements in their outermost orbit by accepting or donating electrons...
Answer and Explanation: Valency is proportional to the number of electrons present in the element's outermost shell. The valency is different for different atoms based on...
For example, the ionization potential decreases with an increasing radius because the valence electrons in the larger noble gases are farther away from the nucleus and are therefore not held as tightly together by the atom. Noble gases have the largest ionization potential among the elements of eac...
