Atom is the smallest particle of matter which may or may not exist independently. Molecule is the smallest particle of matter which can have independent existence. Inert gases exist in atomic state. Oxygen, nitrogen etc. exist in molecular from.
Distinguish between an element and a compound and give an example of each.Atoms:Just as the cell is the smallest and most basic unit of life, the atom is the smallest and most basic unit of matter. Every atom is comprised of a set number of protons and neutrons that are orb...
Despite the astonishing successes of quantum mechanics, due to some fundamental problems such as the measurement problem and quantum arrival time problem, the predictions of the theory are in some cases not quite clear and unique. Especially, there are v
How many different substances are included in this representation? What similarities and differences do you observe between the different types of particles present in the system? The representation conveys the idea that we model air as a “mixture”: Modeling Substances Free atom of argon The repre...
accidents. The total deposition as global fallout has been estimated at 900–1400 kg5,11and from reprocessing plants at 115–250 kg5. This clearly dominates over the natural global inventory of this isotope (a few kg)12. For time-resolved archives, elevated236U/238U atom ratios can be...
In [22], a generalization of the notion of undividedness is considered: at any moment t, an equivalence relation It (indistinguishability at t) between the histories passing through t is given. The only property of the indistinguishability relations is that, if two histories are ...
