This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
Potassium is electron donor
Potassium lose an electron (iodine gain this electron) to form potassium iodide, KI.
Electrons do not pair unless they have to. The correct phrase is "They try to maximize their spin multiplicity. With potassium, the sole 4s electron is unpaired i.e. there is 1 unpaired electron in potassium.
Electrons lose in case of potassium. It looses 1 electron.
Four shells, as potassium is in fourth period
Potassium loses one electron.
one electron
There is only one valance electron in potassium.
It has 4
There is just one valance electron in the element potassium.
Potassium loses one electron. All Alkali metals lose one electron.
Potassium has 19 electrons when it's neutral. It's ionic form is K+. Thus, the potassium ion has one less electron than that, or 18.
Potassium is electron donor
It must lose 1 electron
Potassium lose an electron (iodine gain this electron) to form potassium iodide, KI.
Electrons do not pair unless they have to. The correct phrase is "They try to maximize their spin multiplicity. With potassium, the sole 4s electron is unpaired i.e. there is 1 unpaired electron in potassium.
Potassium has 1 valance electron.
