    Ions which are a part of the science subject Chemistry forms from atoms and electrons that have either gained or lost their weight by the removal or adding of one or more valence electrons which would create either positive or a negative charge. The ions with a negative charge are called anions and the ones with a positive charge are called cations. Since both of them have charges of opposing qualities, they get attracted to one another and thereby forming an ionic bond between them.


When sodium a cation is depicted as NA+, the plus charge indicator shows that it has one electron less than the total number of protons. Thus sodium having an uneven distribution of electrons and protons enables it to have a positive charge. Also the element chloride anion Cl- would denote that it has one less proton than the total number of electrons and giving it a minus charge. The difference between Anions and Cations are provided in the table listed below.

I hope this answers your question!
