Closure temperature radiometric dating
There are a number of implausible assumptions involved in radiometric dating with respect to long time periods.
One key assumption is that the initial quantity of the parent element can be determined.
Historically, these are also known as alpha, gamma, and beta decays, respectively.
"Atomic decays" are due to proton or neutron decays: either weakly, incrementing up or down the table of elements; or strongly, often splitting into smaller elements, one of which is often helium.
Because radiometric dating fails to satisfy standards of testability and falsifiability, claims based on radiometric dating may fail to qualify under the Daubert standard for court-admissible scientific evidence.
It is more accurate for shorter time periods (e.g., hundreds of years) during which control variables are less likely to change.
That is, electrons can move closer to or farther away from the nucleus depending on the chemical bonds.
This affects the coulomb barrier involved in Alpha decay, and therefore changes the height and width of the barrier through which the alpha particle must tunnel.
Electron capture requires that there be an electron in the vicinity of the nucleus, so its activity depends strongly on the configuration of the electron cloud, which depends on the chemical state.
The Be nucleus (Beryllium-7) is an electron capturer with a half-life of about 53 days, turning into Lithium-7. While this half-life is way too short to be useful for radiometric dating, the effect of the chemical state is noticeable.
The reason is that, because the atomic number is only four, the 2s valence electrons are very close to the 1s electrons involved in capture.
The effect of this on alpha decay, which is the most common decay mode in radiometric dating, is utterly insignificant.
There is another effect that takes place in the "electron capture" type of Beta decay.

As early as of 1673, John Ray, an English naturalist, reckoned with alternative that "im the primitive times and soon after the Creation the earth suffered far more concussions and mutations in its superficial part than afterward". Atoms consist of a heavy central core called the nucleus surrounded by clouds of lightweight particles (electrons), called electron shells.
