Science Buddies: "Ask an Expert"

i really dont understand holes in a structure. i read that there are 2n t holes for n o holes. so why is NaCl and other closed packed structures is this not the case? there's like 13 o holes and 12 t holes or something along those lines.

can anyone pleaseeee explain holes to me!

Hi shamyla99,

Is your question related to a K-12 science fair project? If so, what is the hypothesis you are trying to test? If not, then a different set of online forums would be better able to help you. These forums are specifically for K-12 students, parents, and teachers working on science projects.
