Move this slider up and down to simulate the passage of time and see nuclides decay according to their half-lives
What is a Nuclide?
Atoms are made of
protons
What is a Proton?
,
neutrons
What is a Neutron?
, and
electrons
What is an Electron?
. The number of protons in an atom determines what element it is (and thus its chemistry).
Atoms of the same element can, however, have different numbers of neutrons inside their nuclei. More neutrons make an element
heavier without changing its chemistry.
Atoms of the same element with different numbers of neutrons in the nucleus
are called "isotopes" of that element.
Every distinct isotope is a nuclide, or a type of atom found in nature.
Put another way, a nuclide is any
combination of protons and neutrons that can be observed.
Science has discovered 0, nuclides to date
and new ones are still being discovered as time goes on in laboratories around the world!
All nuclides are shown here on the Chart of Nuclides.
It plots neutrons along the
x-axis and protons along the y-axis. The dark line up the middle are the stable
nuclides. These are the versions of elements most commonly found in
nature, like most of the
Carbon
What is Carbon?
in your body and most of the
Oxygen
What is Oxygen?
in the air you're breathing.
Most nuclides are unstable.
When a nuclide is unstable
it will
decay
How do atoms decay?
over time, releasing energy known as
radiation
What is Radiation?
and turning into a more stable nuclide.
Use the slider to simulate the
passage of time and see how
all the different nuclides decay
at very different rates →
