How do knowing the half-life of carbon 14 can tell scientists the absolute age of a rock sample

Chemistry
1 answer:
katrin [286]3 years ago
7 0
Carbon 14 dating makes some assumptions that are not exactly true, but likely close enough for most purposes. 1 that the ratio of carbon 13 to carbon 14 in Earth's atmosphere has not changed over the last million years. 2 that living things give zero preference to carbon 13 over carbon 14.
3 Carbon 14 dating is often unreliable for rocks which have low carbon content, such as quartz, and some other assumptions.

Why are valence electrons important
koban [17]

Explanation:

The electrons in the outermost shell of an atom are the valence electrons. These electrons are the most loosely held in an atom.

The energy required to remove these electrons are not as great as those of the inner shell electrons.

  • Atoms of some elements show no tendency to combine with other  atoms because they have completely filled outer energy levels.
  • Their outermost shell, valence shell and the electron numbers are complete for them. These are the noble gases.
  • other atoms share or exchange their valence electrons in order to have a stable configuration.
  • The valence electrons are involve in inter-atomic bond formation and interactions
  • Also the distribution of these electrons determines inter-molecular interactions between molecules.
