What are the characteristics and properties of lithium?
Lithium is a soft, silvery-white, metal that heads group 1, the alkali metals group, of the periodic table of the elements. It reacts vigorously with water. Storing it is a problem. It cannot be kept under oil, as sodium can, because it is less dense and floats.
What are the properties of lithium chloride?
Lithium chloride is a White cubic crystals; granules or powder; hygroscopic; sharp salt-like taste; melts at 605°C; vaporizes around 1360°C, It has an unusually high water solubility when compared to the other alkali metal chlorides; readily dissolves in water (64g/100mL at 0°C); also highly soluble in alcohol and …

What are the properties and characteristics of alkali metals?
Alkali metals are silvery, soft, and not very dense. They can easily be cut with a butter knife, and cesium can even melt in the palm of your hand. They have low melting points and are incredibly reactive–so reactive that they must be stored in special solutions or containers to prevent an unintended reaction.
What is the difference between the elements lithium and francium?
The element Francium was discovered by Marguerite Perey in year 1939 in France. Francium derived its name from from Francia, the New Latin name for France The element Lithium was discovered by Johan August Arfwedson in year 1817 in Sweden. Lithium derived its name derived its name from the Greek word lithos, meaning ‘stone’
Which of the following is a physical property of lithium?
It is the lightest of the metals, with a density approximately half that of water. Under ordinary conditions, lithium is the least dense of the solid elements. It has the highest specific heat of any solid element.
What are the properties of francium?
Because francium is so rare, it has been very difficult for scientists to gather information about all of its properties. They have learned that it is a solid when it’s at room temperature, and it is very radioactive. Elements that are radioactive give off particles or rays into the air; these are harmful to living things.
Is francium an alkali metal?
Francium is an alkali metal, which means that it can have a violent reaction, like an explosion, if it is mixed with water. The other alkali metals are lithium, sodium, potassium, rubidium, and cesium. These elements are also soft metals, which means they can be easily formed into shapes.
