Atomic Number
An atom can be thought of as being
formed from a number of combined 'H
atoms with additional neutrons in the
nucleus. The mass of an atom is less
than that of the combined masses of
the nuclear particles from which it is
formed. This "mass loss" is an
indication of the stablity of the atom's
nucleus. In order to compare different
atoms, the relative mass loss (in g/mol)
is defined as:
[(number protons x mass of 'H)+(number of neutrons x mass of n)] - atomic mass
number of protons + number of neutrons
The atom's binding energy (the energy
associated with holding the nucleus
together) can be calculated as:
relative mass loss (kg/mol) x (2.998 x 10°m/s)
The resulting units are joules/mole.
Because calculating the relative mass
loss involves dividing by the total
number of nucleons (protons +
neutrons), the binding energy is called
the 'binding energy per nucleon.'

A tiny percent of all naturally-occurring carbon atoms on Earth are carbon-14. Trees (and all living things) incorporate C-14 into their bodies when alive, but this ceases at death, after which the amount of C-14 present gradually decreases due to nuclear decay. Wooden artifacts from long ago can be dated by the percent of carbon-14 remaining in them. A sample of a wooden object from an archaeological site contains only 12.5% of the level of carbon-14 expected for a live tree. How many half-lives have passed since that piece of wood was a living tree?

It determines the stability of the nucleus based on the shielding effect of the neutrons. The neutron to proton ratio describes a radioactive element's half-life. Scientists made up this concept because they wanted to create radiation. An atom's nucleus likes to have the same number of neutrons and protons, so knowing that ratio is important. 00:53:35 PREVIOUS 1 of 20 NEXT SAVEarrow_forward
