Activity Series Of Metals | Science Trends

The activity series of metals relates to the reactivity of metals; the order in which they react always from highest to lowest.. The reactivity of metals is used in order to determine what are the products od single displacement reactions. In single determined reactions, one metal replaces another metal in a solution when the first metal is higher in the series.

Potassium is a chemical element with atomic nuer 19 which means there are 19 protons and 19 electrons in the atomic structure. The chemical syol for Potassium is K. Potassium was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals.

Potassium-40 inside Body - Radiation Dose

A 70-kg man contains about 126 g of potassium (0.18%), most of that is loed in muscles. The daily consumption of potassium is approximately 2.5 gram. Hence the concentration of potassium-40 is nearly stable in all persons at a level of about 55 Bq/kg (3850 Bq in total), which corresponds to the annual effective dose of 0.2 mSv.
