Question

among the electrons revolving around the nucleus which electron will determine chemical properties of an element

Answer 1

The valence electrons determines the chemical properties of an element.

Valence electrons is the electrons present in the last shell of an atom.

The valence electrons determines the valency of an element.

Valency is the combining capacity of an element.

Hence , the chemical properties depends on the valence electrons.

==============================

For example :

Consider the element Sodium(Na)

Atomic no: = Z = 11

No: of protons (p) = Z = 11

No: of electrons(e) = p = 11

Electronic configuration = 2 , 8 ,1

Here , the number of valence electrons is 1.

Hence , valency also is 1.

Thus , the combining capacity of the element sodium is 1

S.H.S

the electron in the outer most shell of an atom will determine chemical properties of an atom because everything like valency can be taken out electronic configuration etc can be taken out with the help of which we can determine whether which period and group the element belongs.
