Use radiometric dating in a sentence
Another possibility is spontaneous fission into two or more nuclides.While the moment in time at which a particular nucleus decays is unpredictable, a collection of atoms of a radioactive nuclide decays exponentially at a rate described by a parameter known as the half-life, usually given in units of years when discussing dating techniques.After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a "daughter" nuclide or decay product.In many cases, the daughter nuclide itself is radioactive, resulting in a decay chain, eventually ending with the formation of a stable (nonradioactive) daughter nuclide; each step in such a chain is characterized by a distinct half-life.
But that which fanaticism formerly promised to its elect, science now accomplishes for all men.Everything tends to show that his convelescence will be brief; and who knows even if at our next village festivity we shall not see our good Hippolyte figuring in the bacchic dance in the midst of a chorus of joyous boon-companions, and thus proving to all eyes by his verve and his capers his complete cure? Honour to those indefatigable spirits who consecrate their vigils to the amelioration or to the alleviation of their kind! Is it not time to cry that the blind shall see, the deaf hear, the lame walk?Blind, Agatha made the curb, wheeling about, seeing us close, all of us yelling, Grandma way ahead, shouting, too, and Agatha off the curb and out in the street, halfway to the middle, then in the middle and suddenly a car, which no one saw, erupting its brakes, its horn shrieking and Agatha flailing about to see and Grandma there with her and hurling her aside and down as the car with fantastic energy and verve selected her from our midst, struck our wonderful electric Guido Fantoccini-produced dream even while she paced upon the air and, hands up to ward off, almost in mild protest, still trying to decide what to say to this bestial machine, over and over she spun and down and away even as the car jolted to a halt and I saw Agatha safe beyond and Grandma, it seemed, still coming down or down and sliding fifty yards away to strike and ricochet and lie strewn and all of us frozen in a line suddenly in the midst of the street with one scream pulled out of all our throats at the same raw instant.A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will undergo radioactive decay and spontaneously transform into a different nuclide.This transformation may be accomplished in a number of different ways, including alpha decay (emission of alpha particles) and beta decay (electron emission, positron emission, or electron capture).
