What are the physical properties of lithium?
Lithium is a very soft, silvery metal. It has a melting point of 180.54°C (356.97°F) and a boiling point of about 1,335°C (2,435°F). Its density is 0.534 grams per cubic centimeter. By comparison, the density of water is 1.000 grams per cubic centimeter.
Chemical properties. In many of its properties, lithium exhibits the same characteristics as do the more common alkali metals sodium and potassium. Thus, lithium, which floats on water, is highly reactive with it and forms strong hydroxide solutions, yielding lithium hydroxide (LiOH) and hydrogen gas.
- Physical. Despite how light it is for a metal, beryllium has a very high melting point. It also has a high modulus of elasticity that is 50% greater than steel, along with a low density giving it a fast sound conduction speed. At STP, beryllium resists oxidation and resists corrosion in the air.
- As we begin our exploration of the third period (row) of the periodic table, we find the element sodium (Na). Being in the first column, sodium is a member of the alkali metal family with potassium (K) and lithium (Li).
- That mineral, petalite, is still a major source of lithium today. Lithium has a number of important and interesting uses. In recent years, it has been used to make lightweight, efficient batteries. Compounds of lithium have also been used to treat a mental disorder known as bipolar disorder.

- While being the lightest metal under normal conditions, it is still the most dense. With an atomic number of three, lithium has three protons in the nucleus, but like many other alkalai metals it has only one valence electron. Interesting Lithium Facts: It is the least reactive of the alkalai metals.
- Lithium reacts intensely with water, forming lithium hydroxide and highly flammable hydrogen. The colourless solution is highly alkalic. The exothermal reactions lasts longer than the reaction of sodium and water, which is directly below lithium in the periodic chart.
- The non-metals or non-metallic elements; hydrogen (H), carbon (C), nitrogen (N), oxygen (O), phosphorus (P), sulphur (sulfer) (S), selenium (Se), (Uuo may belong here) and the noble gases form a relatively small group with a step like pattern towards the left-hand side of the periodic table (hydrogen being the odd one
