They have different numbers of neutrons. All potassium atoms contain 19 protons. Potassium-39 has 20 neutrons while potassium-40 has 21. The extra neutron adds about 1 AMU to the mass of the atom.

What is the decay product of potassium?

The decay product of potassium in a process called beta decay is calcium. Potassium-40 undergoes beta decay to become argon-40, which then decays further to become calcium-40 over a long period of time.


What are geological isobars?

potassium 40, Argon 40, Calcium 40.


What is emitted when potassium -40 decays?

Potassium-40 decays by emitting a beta particle, which is an electron. This decay process transforms potassium-40 into calcium-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.

Can you make potassium hydroxide by mixing potassium sulfate and calcium hydroxide?

No, potassium hydroxide cannot be made by mixing potassium sulfate and calcium hydroxide. Potassium hydroxide is typically produced through the electrolysis of potassium chloride. Mixing potassium sulfate and calcium hydroxide would not result in the formation of potassium hydroxide.


Which has more valence electrons potassium or calcium?

Calcium has more valence electrons than potassium. Potassium has only 1 valence electron, while calcium has 2 valence electrons.


What does potassium-40 break down into over time?

Potassium-40 undergoes beta decay to form calcium-40, along with the emission of a beta particle and a neutrino. This process occurs with a half-life of around 1.25 billion years.
