have a content of up to 98.1%. Naturally occurring lithium (3Li) is composed of two stable isotopes, lithium-6 and lithium-7, with the latter being far more abundant: about 92.5 percent of the atoms.

46.457%

% LI = 13.88/73.89*100 = 18.78% perfectly correct.

It’s important to take lithium as recommended by your doctor. There are 2 different types of lithium – lithium carbonate and lithium citrate. It’s important not to change to a different type unless your doctor has recommended it. This is because different types are absorbed differently in the body.

Solubility of lithium and lithium compounds Elementary lithium is not very water soluble, but it does react with water. Lithium compounds such as lithium chloride, lithium carbonate, lithium phosphate, lithium fluoride and lithium hydroxide are more or less water soluble.

Hence sodium is greater in size than lithium it reacts with water more vigorously than lithium because it is more electropositive metal because of low ionization enthalpy. Therefore we can say that sodium reacts with water more vigorously than lithium because it is more electropositive metal.

In this dramatic demonstration, lithium, sodium, and potassium react with water to produce hydrogen gas and the hydroxides of the metals. Lithium reacts fairly slowly, fizzing. They get softer and more reactive as you move down the period from lithium to sodium to potassium. …

It has the lowest density of all metals. It reacts vigorously with water. The most important use of lithium is in rechargeable batteries for mobile phones, laptops, digital cameras and electric vehicles. Lithium is also used in some non-rechargeable batteries for things like heart pacemakers, toys and clocks.
