Answer:
the hydrogen atom of one water molecule and the lone pair of electrons on an oxygen atom of a neighboring water molecule.
If the units for gases were the same as the units for numbers would be too small to be convenient.
For example, the density of iron is 7.87 g/cm³.
Using the same units, the density of hydrogen is 0.000 0899 g/cm³.
It is much more convenient to express the density in numbers that are easier to visualize: 0.0899 g/L, and that is still a small number.
J.J Thompson’s model shows a sphere with electrons that are moving around freely. However, Thompson’s model does not show protons or neutrons. The model that we have today gives a clearer structure showing protons, neutrons, and electrons inside an atom.
