number (6.02214076 × 1023) is the number of molecules that constitutes the atomic weight of a molecule in grams (g). For example, water is two hydrogen atoms with a weight of 1 g each and one oxygen atom with a weight of 16 g, meaning that one mole of water molecules weighs 18 g...
1. The total energy of an atom or molecule is due to many energetic contributions, both kinetic and potential. Consider a beryllium atom as an example. My drawing below identifies the motions and interactions and how many of each - that con...
