Forms of radiometric dating Privat adult cam chat

Some nuclides have very long half-lives, measured in billions or even trillions of years.

Others have extremely short half-lives, measured in tenths or hundredths of a second.

In electron absorption, a proton absorbs an electron to become a neutron.

In other words, electron absorption is the exact reverse of beta decay.

Uraniums abbreviation is U, so uranium-238 can be more briefly written as U238.

When I first became interested in the creation-evolution debate, in late 1994, I looked around for sources that clearly and simply explained what radiometric dating is and why young-Earth creationists are driven to discredit it.

Some, however, are unstable -- given time, they will spontaneously undergo one of the several kinds of radioactive decay, changing in the process into another element.

There are two common kinds of radioactive decay, alpha decay and beta decay.

Since all atoms of the same element have the same number of protons, different nuclides of an element differ in the number of neutrons they contain.

For example, hydrogen-1 and hydrogen-2 are both nuclides of the element hydrogen, but hydrogen-1's nucleus contains only a proton, while hydrogen-2's nucleus contains a proton and a neutron.
