This is a list of prices of chemical elements.Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison.
This means that 1 gram of sodium chloride contains approximately 393.4 mg of elemental sodium. [94] For example, to find out how much sodium chloride contains 1500 mg of elemental sodium (the value of 1500 mg sodium is the adequate intake (AI) for an adult), we can use the proportion:

An adult body has 22–26 grams of magnesium, [15] [113] with 60% in the skeleton, 39% intracellular (20% in skeletal muscle), and 1% extracellular. [15] Serum levels are typically 0.7–1.0 mmol/L or 1.8–2.4 mEq /L. Serum magnesium levels may be normal even when intracellular magnesium is deficient.
The level of radioactivity is such that during 100 years, the lava's self irradiation (2 × 10 16 α decays per gram and 2 to 5 × 10 5 Gy of β or γ) will fall short of the level required to greatly change the properties of glass (10 18 α decays per gram and 10 8 to 10 9 Gy of β or γ).
