Isotopes Explained: Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally occurring, variations of neutron quantities as...

Atomic mass is expressed in atomic mass units (amu) for a single atom and in grams per mole for macroscopic quantities. A mole is quantified as Avogadro's number (6.02 × 1023) of atoms. An atom of a given element always has the same number of protons. If it had a different number,...
Such animals need large quantities of liquid water.Evolutionists, with their eons of time and multiple ice ages, believe that Siberia and Alaska are relatively warm at present,29 compared with the time when mammoths lived there. So, how could these large populations of animals have lived in ...
39–40). Explicitly in order “to facilitate exchanges […] it has been found necessary […] to affix a publick stamp on certain quantities of such particular metals. […] Hence the origin of coined money” (Smith 1976, p. 40). The mints that create these coins evaluate the purity ...
having fallen as cosmic rays and becoming trapped in ice at –120°C. Aksenov says the first question he’s usually asked is whether they’ll be in enough quantities to have a practical use: a copernicium nuclear plant to solve the energy crisis, or an atom bomb that could level a city...
However much we (rightly) desire to to lock our measurements to quantities we perceive to be constant, we always need some physical phenomenon with such unvarying properties that we can use it as a standard. Le Grand K and it's copies were pretty good for most practical needs, and may ev...
