Which quantity must be determined experimentally in order to determine the bonding atomic radius of an atom? (a) The distance from the nucleus where the probability of finding an electron goes to zero. (b) The distance between the nuclei of two atoms that are bonded together. (c) The effective nuclear charge of an atom.

Hey everyone in this example, we need to determine which of the below measurements would help determine the bonding radius of an atom. So what we should think of is two atoms here. Well, just represent them by circles and we want to imagine their nucleus is so we'll represent them as these dots in the middle. We want to recall that if we measure the distance between these two nuclei of these two atoms that are being bonded to one another, this is going to be our or this is going to help us determine our bond length. And this would therefore also help us determine our bonding radius. And so that means that we can conclude that choice D. Is the only correct answer choice to complete this example. So I hope that everything I explained was clear. If you have any questions, please leave them down below. Otherwise I will see everyone in the next practice video.
