Atoms 'like' to have 8 valence electrones. sodium has one electron 'in excess' and chlorine 'lacks' in one. so they just exchange :) both are happy. then the ionic bond is formed because chlorine is now charged negative (additional electron) and sodium is charged positive (gave up one electrone) - the opposite charges cause electrostatic pull. many atoms, many bonds and thats how salt is built.
It matters to the aerodynamics of it because sometimes it's good to have the weight but only if it can take it.
Rubidium : Rb : Atomic number 37 : Atomic mass : 85.47
Bent, the lone pair on the central atom push away the other atoms and the most stable configuration of the lone pair and two atoms is trogonal planar. But since you cannot see the lone pair, the shape of the three atoms is bent.
Hey not really an answer but just needed someone to talk to you
