I am trying to find out what it means when for instance the density of lead is higher than that of iron.
A = Z + N mass number is atomic number plus number of neutrons, for a chemical element.
When we say that a nucleus contains more protons and neutrons compared to another element,
does that mean :
- the nucleus volume has increased compared to the whole atom size,with atom size staying the same
- or nucleus volume stayed the same but increased in density,meaning p and n closer together.
-or did the atom size increase also, and…
-or …
So i am trying to pinpoint exactly what a higher density means on (sub)atomic level.
