The atomic number of potassium is 19, which means it has 19 protons in its nucleus.
One potassium atom can combine with one chlorine atom to form potassium chloride.
The mass number for potassium is 39. This number represents the total number of protons and neutrons in the nucleus of a potassium atom.
One unit of potassium iodine contains two atoms: one atom of potassium and one atom of iodine.
The chemical formula for potassium iodide is KI. It is composed of one potassium (K) atom and one iodine (I) atom, bonded together.
The atomic number of potassium is 19, which means it has 19 protons in its nucleus.
Every atom of potassium has a mass of 39 amu. Each mole of potassium has a mass of 39 grams.
39.0983 or 39
lose only one electron
The atomic number of potassium is 19.The atomic weight of potassium is 39,0983(1).The mass number of the isotope potassium-39 is 39.
Potassium bromide contains potassium atoms (chemical symbol K) and bromine atoms (chemical symbol Br).
The element is potassium. Atomic mass is 38.
The chemical formula of potassium hydroxide is KOH: 1 atom of potassium, 1 atom of oxygen, 1 atom of hydrogen.
Since potassium chloride has the formula KCl and the mass of the lost electron from neutral potassium is negligible compared with the mass of the protons and neutrons in the potassium atom nucleus, the molecular mass of potassium in this compound is the same as the atomic mass of potassium, 39.098.
Potassium 31 is potassium's normal state, the way you would find it on the Periodic Table. I presume potassium 41 is an isotope of potassium. (An isotope is the same atom, but it has a different number of neutrons, so the mass differs.)
The mass number is always the sum of the numbers of protons and neutrons and therefore is 39 in this instance. The atomic number of 19 shows that the atom is of the element potassium, and its symbol is 39K.
There are two elements in potassium chloride. One atom of potassium and one atom of chlorine react to form potassium chloride.
