Potassium has multiple isotopes, such as potassium-39 and potassium-41, which have different numbers of neutrons in their nuclei. These isotopes do not affect the chemical properties of potassium, but they have different atomic masses due to the differing number of neutrons.
There is only one valance electron in potassium.
It is difficult to write chemical formulae correctly in this forum but this is the best I can do - hopefully you will recognise how it should be written correctly ie with numbers written smaller and low down. C6H7KO2
The three numbers on a bag of fertilizer represent the percentage by weight of nitrogen, phosphorus, and potassium, respectively. These numbers are known as N-P-K ratios and indicate the concentration of these essential nutrients in the fertilizer.
the answer is 21. because you do 40-19
K2UO4 Note the numbers should be subscripts.
The numbers 39, 40, and 41 after the element name potassium refer to the mass number of the isotopes of potassium. Potassium has three isotopes: potassium-39, potassium-40, and potassium-41, which have 19, 20, and 21 neutrons respectively.
chlorine plus potassium bromide gives bromine plus potassium chloride. Here is the symbol equation, but remember that the numbers AFTER the symbols should be subscripts. Cl2 + 2KBr = Br2 + 2KCl
Always +1
No

K - Potassium. Just look at atomic numbers on periodic table! potassium

It is not safe or recommended to make potassium at home due to its highly reactive nature. Potassium is a chemical element that should be handled by professionals in controlled environments. Attempting to make potassium at home can be extremely dangerous and should be avoided.

YES. A normal potassium level is 3.5 to 5.5. You should definitely talk to your doctor about this.
Potassium sorbate should be added to wine before bottling to prevent further fermentation and spoilage.
