The forces acting between any sodium and any adjacent chlorine ion are equal. Solution:- (B) Protons− 11, electrons− 10, neutrons− 12. However, sodium and chlorine respond together to generate a substance that is familiar to nearly everybody in the globe that is sodium chloride, or table salt, or common salt. Register with BYJU’S to learn more on the topic and several other topics of chemistry. Your email address will not be published. Answer 10 Atomic Structure. Each ion is 6-coordinate and has a local octahedral geometry. It is best thought of as a face-centered cubic array of anions with an interpenetrating fcc cation lattice (or vice-versa).
