Question

4) a. What is the reason for positive charge on a sodium ion and a
negative charge on a chloride ion in the formation of sodium
chloride?​

Answer 1

Answer:

It is clear that a sodium ion has one electron less than the electrically neutral sodium atom. In a sodium ion, the number of protons is more than the number of electrons, which gives the ion an overall positive charge of one unit. A proton has an overall positive charge and an electron has an overall negative charge.

Answer 2

Answer:

as na has one electron in its outermost shell and cl has seven electron in its outermost shell it is easy to share one electron so na has + charge while cl - charge please follow me and mark as branliest answer
