Does potassium-40 have electrons?
Potassium-40 is a rare example of an isotope that undergoes both types of beta decay. In about 89.28% of events, it decays to calcium-40 (40Ca) with emission of a beta particle (β−, an electron) with a maximum energy of 1.31 MeV and an antineutrino….Potassium-40.

How many electron does K+ have?
19 electrons
This tells us that in an atom of K there are 19 protons and 19 electrons. c. But we are considering the cation K+. The plus sign indicates that there is one more proton than electron in this ion.
How many neutrons are in a neutral atom of K 40?
Potassium 40 contains odd numbers of both – 19 protons and 21 neutrons.
How many neutrons does K 39 have?
twenty neutrons
Potassium-39 has twenty neutrons.
How many electrons CA?
20 electrons
A calcium atom has 20 protons and 20 electrons.
What does the symbol 39 19 K mean?
It is the number under the element symbol. For potassium it is about 39. This means that the atomic weight is 39 for both protons and neutrons. Since we know that the number of protons is 19 we can calculate the number of neutrons (39 19) as 20.
What is the element 42k?
