atoms are tiny indivisible particles.
the atoms of any one element are different from those of any other element.
compounds are made by combining atoms.
atoms of different elements can combine with one another in simple whole number ratios.

Why is an elements atomic mass not listed as a whole number on the periodic table

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?
