is the second mentioned metal above is safe ?
No, it forms flammable hydrogen and caustic sodium hydroxide on contact with water; ingestion and contact with moisture on skin, eyes or mucous membranes can cause severe burns.
Sodium
Sodium forms flammable hydrogen and caustic sodium hydroxide on contact with water; ingestion and contact with moisture on skin, eyes or mucous membranes can cause severe burns.
why alkali metals have low melting and boiling points It is because metal atoms are held together by the electromagnetic attraction from the positive ions to the delocalised electrons. what are they ? They are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1. give some examples of them ? Lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). what is the pricing of the first mentioned metal ? After the 2007 financial crisis, major suppliers, such as Sociedad Química y Minera (SQM), dropped lithium carbonate pricing by 20% and it rose in 2012. is it used for air purification ? Yes, lithium hydroxide and lithium peroxide are the salts most used in it. the above company who dropped their prices where is it located ? Its headquartered in Santiago. what other products it offers ? Plant nutrients, iodine and industrial chemicals

Sodium [SEP] Safety and precautions
Sodium forms flammable hydrogen and caustic sodium hydroxide on contact with water; ingestion and contact with moisture on skin, eyes or mucous membranes can cause severe burns. Sodium spontaneously explodes in the presence of water due to the formation of hydrogen (highly explosive) and sodium hydroxide (which dissolves in the water, liberating more surface). However, sodium exposed to air and ignited or reaching autoignition (reported to occur when a molten pool of sodium reaches about 290 °C) displays a relatively mild fire. In the case of massive (non-molten) pieces of sodium, the reaction with oxygen eventually becomes slow due to formation of a protective layer.
