Lepidolite is a lilac-gray or rose-colored member of the mica group of minerals with chemical formula K(Li,Al) 3 (Al,Si,Rb) 4 O 10 (F,OH) 2. [2] [3] It is the most abundant lithium-bearing mineral [4] and is a secondary source of this metal.
There are many types of magnesium, each with its benefits. Here, experts explain the most common types and what to use each for. There Are More Than 10 Types of Magnesium—Which Should You Take?
Up to 10% of the potassium may be replaced by sodium, and up to 20% of the hydroxide by fluorine. Chlorine rarely replaces more than 1% of the hydroxide. Muscovite in which the mole fraction of silicon is greater than aluminium, and magnesium or iron replaces some of the aluminium to maintain charge balance, is called phengite. [12]
electropositive metals with values between 1.4 and 1.9; and electronegative metals with values between 1.9 and 2.54. From the image, the group 1–2 metals and the lanthanides and actinides are very electropositive to electropositive; the transition metals in groups 3 to 12 are very electropositive to electronegative; and the post-transition ...

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
