How does potassium turn into argon?
Potassium-40 undergoes radioactive decay into argon-40. During this process, a potassium atom undergoes electron capture where a proton in the nucleus captures an inner-shell electron and is transformed into a neutron. The result is the transformation of a potassium atom into an argon atom by emitting an electron and an antineutrino.
Number of electrons in argon- 40 atom?
Argon-40 atom has 18 electrons.
What is the daughter product of potassium-40?
The daughter product of potassium-40 is argon-40, which is formed through the process of radioactive decay. Potassium-40 undergoes electron capture to become argon-40, releasing a neutrino and a positron in the process. Argon-40 is stable and does not undergo further decay.
What is the mass number of the atom of argon?
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
How is argon formed?
Argon is formed through the radioactive decay of potassium-40 in the Earth's crust. Potassium-40 undergoes a series of decay reactions, ultimately producing argon-40 as a stable end product. This process occurs over millions of years and is responsible for the presence of argon in the Earth's atmosphere.

What characteristics do atoms argon-40 potassium-40 and calcium-40 have in common?
Atoms argon-40, potassium-40, and calcium-40 all have 40 protons, but differ in the number of neutrons in their nuclei. They are all stable isotopes, with no natural radioactivity.
How is Potassium argon used to date the age of a rock?
Potassium-argon dating is a radiometric dating method that determines the age of rocks by measuring the ratio of potassium-40 to argon-40. This technique is based on the fact that potassium-40 decays into argon-40 over time at a known rate. By comparing the amount of argon-40 present in a rock sample to the amount of potassium-40, scientists can calculate the age of the rock.
Number of electrons in argon- 40 atom?
Argon-40 atom has 18 electrons.
How many years old is argon -40?
Argon-40 is a stable isotope with a half-life of 1.25 billion years. To determine its age, scientists measure the ratio of argon-40 to potassium-40 in a sample, which allows them to calculate the age of the sample based on the decay of potassium-40 to argon-40.
What is the daughter product of potassium-40?

What characteristics do atoms of argon-40 potassium-40 and calcium-40 have in common?
Argon-40, potassium-40, and calcium-40 all have 40 protons and electrons in their atoms, but they have different numbers of neutrons. They are all stable isotopes, although potassium-40 is radioactive and undergoes decay to form argon-40.
What are geological isobars?
potassium 40, Argon 40, Calcium 40.
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.
