You can get it online from science suppliers online like United Nuclear. But you will need an adult to sign the package on delivery, and also pay a 20 dollar hazmat fee as potassium is dangerously reactive.

The element with 19 protons is potassium, which is represented by the symbol K on the periodic table.
Potassium has 19 electrons.
The electrical conductivity of potassium is high because it is a metal. Potassium atoms can easily lose electrons to form positive ions, allowing electric current to flow through a potassium sample.
Potassium-40 decays by emitting a beta particle, which is an electron. This decay process transforms potassium-40 into calcium-40.
In a flame test, the color released by potassium is lilac, which is a light purple. K is the symbol for the chemical element potassium, and its atomic number is 19.
Potassium + Chlorine --> Potassium Chloride (potassium plus chlorine arrow potassium chloride)
I believe it is Potassium Hydride. I believe it is Potassium Hydride.
KNO3 is the chemical formula of potassium nitrate.
i think either potassium(II) sulfate or potassium sulfate
KCl = Potassium Chloride KOH = Potassium Hydroxide KNO3 = Potassium Nitrate KMnO4 = Potassium Permanganate
The compound name for K3PO2 is potassium hypophosphite.
I believe 24 isotopes have been identified with atomic mass ranging from 32 to 55. Only three occur naturally, K39 (93% of the total), K41 (7%) and the radioactive K40 (0.01%). The others have very short half-lives, as small as a few nano-seconds in some cases.
The first element in the fourth period of the periodic table is potassium with the atomic number 19.
There are 2 elements in potassium oxide, which are potassium and oxygen.
Potassium Cyanide, because K is the symbol for Potassium and CN represents cyanide.
Potassium, K+, is a cation
"Potassium bromide"
