Answer:-
Valence electrons are the outermost electrons of an atom, found in the outer shell or energy level. These electrons play a key role in chemical bonding because they are involved in forming bonds with other atoms. The number of valence electrons determines an element’s reactivity and its ability to bond with others. For example, elements in the same group of the periodic table have the same number of valence electrons, which gives them similar chemical properties. In general, atoms tend to gain, lose, or share valence electrons to achieve a stable electron configuration, often resembling that of noble gases.
