How protons electrons and neutrons relate to an atom's characteristics

[Vacrin]

So i was wondering if perhaps a atoms electrons protons and neutrons determine all of its characteristics, such as the hydrogen atom. having only one electron and one proton. it makes it turn into a liquid and solid very close together, and a gas anything above about -259.1°C. and the characteristics of all the others, determined by their particles. it may sound crazy but might it be possible?

Bulk properties are generally considered emergent from simpler underlying rules - the atomic structures being key.
However, bulk properties are not entirely defined by the atomic structure of it's constituents - i.e. a solid may have a crack in it ... the structure of the crack is not predictable from the atomic structure.

But then - emergent properties are seldom predictable.
