is lithium a metal? Yes,  a soft, silvery-white alkali metal. what is meant by this last term? The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they constitute group 1 how is it connected to our solar system? All the alkali metals have odd atomic numbers and they are not as common as the elements with even atomic numbers adjacent to them (the noble gases and the alkaline earth metals) in the Solar System. where it is applied? Lithium is often used in lithium-ion batteries, and lithium oxide can help process silica. Sodium compounds have many applications, the most well-known being sodium chloride as table salt. Potassium compounds are often used as fertilisers which among them are the heavy ones? UNANSWERABLE what is the biological role of the aforementioned metal on which our conversation started? Lithium is found in trace amount in numerous plants, plankton, and invertebrates can you mention any one precautions while handling it? Lithium is safely stored in non-reactive compounds such as naphtha. Breathing lithium dust or lithium compounds (which are often alkaline) initially irritate the nose and throat, while higher exposure can cause a buildup of fluid in the lungs, leading to pulmonary edema. why is it required in astronomy? Astronomers reported that classical novae explosions are the galactic producers of lithium. what exactly is the disease that you have mentioned above in the last? Pulmonary edema is fluid accumulation in the tissue and air spaces of the lungs. It leads to impaired gas exchange and may cause respiratory failure.

Pulmonary edema [SEP] Types
Classically it is cardiogenic (left ventricular) but fluid may also accumulate due to damage to the lung. This damage may be direct injury or injury mediated by high pressures within the pulmonary circulation. When directly or indirectly caused by increased left ventricular pressure pulmonary edema may form when mean pulmonary pressure rises from the normal of 15 mmHg to above 25 mmHg. Broadly, the causes of pulmonary edema can be divided into cardiogenic and non-cardiogenic. By convention cardiogenic refers to left ventricular causes.
