its either a proton, an atom, a molecule, or an element. But im not sure which one it is. So keep that in mind.
For an element, it would be an atom. For a molecular substance, it would be a molecule. If it is an ionic compound, it would be a formula unit.

physical properties
Intensive properties are independent from the mass of an object: density, hardness, melting point.
Temperature and amount of the substance do not change chemical properties.

A substance's characteristic properties are the most recognizable properties of that substance. Chemical properties are exhibited as one substance is chemically transformed into another (e.g., iron rusting).
Smooth is what it feels like; square and tan are what it looks like - those would all be physical properties of the substance.
physical properties
I take this to be what the properties of the new substance would be. That depends on what the two original substances were.
A molecule is the smallest unit with the characteristic properties of a molecular substance, i.e., one joined by covalent bonds. A single atom is the smallest unit with the characteristic properties of an elemental substance.
A chemist, in describing all the properties of "Substance A" would note that "Substance A is insoluble in water".
Intensive properties are independent from the mass of an object: density, hardness, melting point.
When a substance changes, any or all of its properties can also change.
