Question

the chemical properties of an element depend on the number of electrons in the outermost shell of its atom.justify it.

Answer 1

The electron configuration of an atom is the representation of the arrangement of the electron distribution distributed among the orbital shell and subshell full stop commonly the electron configuration is used to describe the orbital of an atom in its ground state but it can also be used to represent an atom that has organised into a cation or anion by compensation compensating with the loss of or gain of electrons in their subsequent orbitals many of the physical and chemical properties of elements can be correlated to their unique electron configuration first of the valence electrons of electrons in the outermost shell are the
determining factors for the unique chemical chemistry of the element.

Answer 2

Explanation:

the the chemical properties of an element is dependent on the number of electrons in their arrangement as the number of electrons constituting the atomic number of an element and atomic number is the fundamental property of an element.like some of the elements for example sodium has one electron in its outermost orbit so it has the tendency to lose one electron to become stable likewise oxygen has 6 orbits in its valence shell so it has the tendency to gain two electrons to become stable similarly neon which has 8 electrons in its outermost shell do not have any tendency to lose or gain the electrons as it is already stable in nature.
