40-Argon is formed by the radioactive decay of 40-Potassium. 40-Argon is stable so it could have been created from the potassium 4 billion years ago or yesterday; or even 5 nanoseconds ago.

What is potassium argon dating?
The radioactive decay of potassium 40 produces in argon 40. The proportion of these two isotopes in rocks permit their age to be calculated.
What is the volume occupied by 40 grams of argon gas Ar at standard conditions?
It is 22.413 litres, approx.
How does argon naturally occur?
Argon occurs as a result of the radioactive decay of 40K ( potassium 40 ) Potassium is common on Earth; about 1/60th of it's crust is potassium. Naturally occurring potassium is a mixture of three isotopes. Almost all of it is 39K and 41K, both of which are stable. About 1 atom in 10,000 is 40K, which is unstable. It has a very long half-life, >109 years; it decays to 40Ar which is stable.
What object contains argon?
Argon is a chemical element that is a part of the Earth's atmosphere. It is a noble gas and is present in trace amounts (about 0.934% by volume) in the atmosphere. Additionally, argon can be found in certain minerals and rocks, such as potassium-bearing minerals, as it is produced through the radioactive decay of potassium-40. However, argon is not typically found in significant quantities within specific objects; instead, it is more commonly encountered as a component of the atmosphere.
