What are three types of radiometric dating?
These are three ways to find out how old a rock is. There's radiocarbon dating, potassium-argon dating and uranium-lead dating. Does this help?
If argon is 18 then what is 19?
K - Potassium. Just look at atomic numbers on periodic table! potassium
Compare and contrast two types of radioactive decay?
you have to know what radioactive decay is.
How many years old is argon -40?
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.
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 is KAr dating?
It is the abbreviation for a form of radiometric dating called Potassium Argon dating (K = Potassium and Ar = Argon).
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 problematic about the potassium argon method of radiometric dating?
Argon is a gas that may leak from a sample and provide inaccurate data

Which method for determining the age of artifacts measures the rate of decay in atoms in volcanic rock?
The method used for determining the age of artifacts by measuring the rate of decay in atoms in volcanic rock is radiometric dating, specifically the potassium-argon dating technique. This method relies on the radioactive decay of potassium isotopes into argon isotopes in volcanic rock to determine its age. By measuring the ratio of potassium to argon isotopes, scientists can calculate the age of the rock and any artifacts contained within it.

What are two types of dating?
The two types of radioactive dating that are most common are: Carbon 14 and Potassium-Argon. There are quite a few others.
Could the potassium argon method of radiometric dating be used to date rocks that are estimated to have formed 1000 years ago?
No. Potassium decays to argon, and geologists measure argon as the daughter material. The half life is too long for 1000 years to give sensible results.
Which method for determining the age of artifacts measures the rate decay in atoms in volcanic rock?
potassium-argon dating
What is the nearest noble gas to potassium?
Argon (Ar) is the nearest noble gas to potassium.
The carbon-14 method of dating differs from the potassium-argon and the uranium-lead methods of dating by using what?
The carbon-14 dating method differs by using the decay of carbon-14 isotopes to determine the age of organic materials up to around 50,000 years old, while potassium-argon and uranium-lead methods are used for dating older rocks and minerals. Carbon-14 dating is primarily used for relatively recent materials, while potassium-argon and uranium-lead methods are used for dating geological samples millions to billions of years old.
Which element had the largest atom potassium or argon?
argon
