I know all the properties what i mentioned below are having database values for all the elements.

But my query is

What is the equipment/DEVICE/ GADGET/machine/ is used to measure
---ionisation energy
---lattice enthalpy
---atomic radius
---bond length
---BOND ENTHALPY
--ENTHALPY OF FORMATION
---ENTHALPY OF ATOMISATION
---ELECTRON AFFINITY.

You have to show your attempts at answering the problem to receive help, this is a forum policy.

What does "experimental determination of ionization energy" search return?

[Enthalpy]

Many of these properties are not measured directly. They are deduced from other properties: density, heat of combustion, vapour pressure versus temperature, and so on.

But we want to read your attempts before giving more hints, it's the way this forum works.
