See if this helps at all!

It's difficlut to answer the question because of the question itself. Orbitals and electron spin etc are part of quantum mechanics, and quantum mechanics is a mathematical model and really can’t be translated into a simple, what I call, ball and sticks, model very easily. For example we talk about electron spin, but electrons aren’t spinning like little balls because they have no size! Also it is impossible to locate the position of an electron, so bumping into each other is not a concept.

Orbitals are regions of space where there is a high probabability of the electron being located and those funny dumbbell shapes etc are just that, regions of mathematical probability, the denser the orbital the more probable the electron is located there. When orbitals overlap that just gives a region where there is greater probability that the electron is there. The closest we could say to a simple ball model is the electrons spend more time there. That’s what causes two atoms to bond together, like two hydrogen atoms. The two 1s orbitals overlap so the two electrons spend more time between the atoms and therefore making a negative region between will hold (or bond) the two positive proton nuclei together.

And ionic bonding is a type of bonding because atoms, whose electrons have been transferred to other atoms, are attracted to each other, or bonded. There are other types of bonds. Bonds are just attractions. Molecules are bonded to each other. That explains why water is liquid and not a gas. Metal atoms are bonded to each other, so most metals are solids at room temperature.

So the real answer is, it is very difficult to picture atoms in a mathematical, quantum mechanical, model.

Not written by me I must add!
