# Write an equation for the decay of potassium 40 to argon 40 protons

. Report Abuse Atomic number, atomic mass, and isotopes Video transcript We know that an element is defined by the number of protons it has. We look at the periodic table of elements. What is the nuclear decay equation for potassium A curiosity of Nature and a very long lived beta emitter Argon 40, a gas held prisoner by lava The potassium-argon method is frequently used to date lava flows whose age is between a million and a billion years. Radiometric dating Potassium—argon dating[ edit ] Decay scheme Potassium is especially important in potassium—argon K—Ar dating. The purpose of this chapter is to explain the process of radioactive decay and its relationship to the concept of half-life. Remember that a radionuclide represents an element with a particular combination of protons and neutrons nucleons in the nucleus of the atom.

There are three beta decay modes for 40K, and so three equations. The equation for the negative beta decay of 40K: The equation for the positive beta decay of 40K: The equation for the decay of 40K by electron capture is: The equation for the alpha decay of Ra: What is the nuclear decay equation for iodine?

Here is the equation for the beta minus decay of iodine The iodine undergoes a transformation when a down quark within a neutron in its nucleus changes into an up quark.

This change is mediated by the weak interaction, or weak force. The neutron then becomes a proton, and an electron is created and ejected from the nucleus along with an antineutrino.

To learn more, use the link below to the related question, "What is beta decay? Be aware that this decay process could be extremely harmful to those around it. Thanks for asking though, fancy a date?? The equation for the beta decay of 32 P: The daughter atom is sulfur and has an atomic number of What is the nuclear equation for the decay of iodine?

There are a number of different isotopes of iodine, each of which has its own way of decaying and its own decay equation. There is a link to one below. What is the nuclear decay equation for the beta decay of copper?

There are a number of radioactive isotopes of copper, choosing 66 Cu as on that undergoes negative beta decay, the equation is: Where e represents the beta particle, which can also be viewed as an electron. What is the nuclear equation for alpha decay of polonium?

Polonium alpha particlesLead Polonium alpha particlesLead Polonium alpha particlesLead For other isotopes see the list at: The equation for the alpha decay of At: What is the nuclear decay equation for cobalt?

The equation for the beta decay of 60 Co is:Each potassium atom contains 19 protons "p"^+ and thus an average potassium atom contains about - 19 ~~ 20 neutrons "n"^0.

## A curiosity of Nature and a very long lived beta emitter

Can you write the nuclear equation for the decay of potassium? Chemistry Nuclear Chemistry Nuclear Equations. 1 Answer Can you write a balanced nuclear equation for the alpha decay of Ra? Sep 06,  · Best Answer: Beta decay is the release of a high speed electron from the nucleus. 19K40 --> -1e0 + 20Ca40 The production of Ar would come from the release of a positron or a "beta-plus", B+, which is a particle of iridis-photo-restoration.com: Resolved.

There are three beta decay modes for 40K, and so three equations. The equation for the negative beta decay of 40K: K --> Ca + e where the e represents a beta particle or electron.

The equation for the positive beta decay of 40K: K --> Ar+ 10e where the 10e represents a positive beta particle or positron. Potassium is found in bananas, and it has so many neutrons compared to its number of protons that it turns a neutron into a proton!

The nucleus of the atom is super unstable (or unhappy) and to make it more stable, it needs to undergo beta decay.

Potassium has a half-life of billion years. Daughter isotope is argon When rock is produced from lava, all the gases in the molten rock, including argon, . This particular isotope of potassium contains #42# nucleons (i.e., protons and neutrons, combined;) Like other isotopes of potassium #19# out of these nucleons are protons; the rest #42 - 19 = 23# are therefore neutrons.
