The atomic number of potassium is 19. The mass number is the number of protons plus the number of neutrons. The three natural isotopes of potassium have mass numbers of 39, 40, 41. Properties of Potassium-41 Isotope: POTASSIUM-41; Natural Abundance (%) 6.73: Atomic Mass (Da) 6: Relative Isotopic Mass: 6: Neutron Number (N). Here is the generic procedure. Step 1: For the number of protons, it is equal to the atomic number. You can look up the atomic number for any element on the Periodic Table of the Elements, or any Table of the Elements. If you know the element’s.
About Potassium
One of the vital elements for all living creatures, potassium exists in all living cells. Potassium is a very soft metal of light grey color which is very reactive with air and other chemical compounds. It is considered to be the 7th most abundant chemical element in the earth crust and it is usually processed from potassium chloride, which is quite abundant too. Potassium is essential for the cells of living organisms to maintain proper electrolyte and fluid balance. Daily dose of potassium for a human body is close to 7 grams, and we receive it mainly from foods like chocolate, nuts, bananas, potatoes, raisins, etc. This chemical element is used for producing fertilizers, and potassium also is important for producing glass. Various compounds involving potassium are heavily used in pharmaceutical industry.
