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 first decay products of potassium-40 are argon-40 and calcium-40.
Will calcium chloride and potassium react?
Yes. The potassium will replace the calcium in the calcium chloride, producing potassium chloride and calcium. This is an example of a single replacement/displacement reaction. CaCl2 + 2K --> 2KCl + Ca
Which has more valence electrons potassium or calcium?
calcium
Which has more atoms calcium hydroxide or potassium phosphate?
Calcium Hydroxide is Ca(OH)2 and potassium phosphate is K3PO4. So calcium hydroxide has 5 atoms and potassium phosphate has 8 atoms. So potassium phosphate has the most atoms.
Is the abbreviation for calcium is K?
No, K is potassium; calcium is Ca.
What is the decay product of potassium?
The first decay products of potassium-40 are argon-40 and calcium-40.
What are geological isobars?
potassium 40, Argon 40, Calcium 40.
What characteristics do atoms of argon-40 potassium-40 and calcium 40 have in common?
They have the same mass.
What characteristics do atoms argon-40 potassium-40 and calcium-40 have in common?
They have the same mass.
What characteristics do atoms of argon-40 potassium-40 and calcium-40 have in common?
They have the same mass.
What are example of isobar?
Isobarsargon-40, calcium-40, sulphur-40, potassium-40 are example of isobars....
Is calcium or potassium an hallogen?
Calcium or Potassium are not halogens but metals.
Will calcium chloride and potassium react?
Yes. The potassium will replace the calcium in the calcium chloride, producing potassium chloride and calcium. This is an example of a single replacement/displacement reaction. CaCl2 + 2K --> 2KCl + Ca
What are the formulas for calcium chloride and potassium phosphate?
Calcium chloride: CaCl2 Potassium phosphate: K3PO4
Mineral found in bones?
calcium, potassium, zinc, iron, phosphorus
Can you make potassium hydroxide by mixing potassium sulfate and calcium hydroxide?
Yes, the potassium and the hydrogen will bond together, leaving the sulfate and calcium.
Which has more valence electrons potassium or calcium?
calcium
