lithium (Li), chemical element of Group 1 (Ia) in the periodic table, the alkali metal group, lightest of the solid elements. The metal itself—which is soft, white, and lustrous—and several of its alloys and compounds are produced on an industrial scale.
Is lithium soft?
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.
Why is lithium harder?
Li has anomalous properties due to very small size and high polarizing power. Lithium is much harder than the other alkali metals due to strong metallic bonds.
Is lithium strong and hard?
Lithium (from Greek: λίθος, romanized: lithos, lit. ‘stone’) is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the least dense metal and the least dense solid element.
Why is lithium not soft?
Lithium is pretty; a shiney silvery alkali metal. It is so soft it can be cut with scissors and it’s so light that it floats on water. But it’s also extremely reactive so it doesn’t stay shiney or silvery very long. For this reason, it is never found “in the wild” in its pure elemental form (on earth).
Is lithium a malleable?
In the form of a simple element, lithium, is a malleable, soft, light metal of a silvery color.
How does lithium make you feel?
Lithium may take several weeks or months to work. How will it make me feel? If the amount of lithium in your blood is right, you probably will not have any problems taking this medicine. However, some people find it slows down their thinking or makes them feel a bit “numb”.
Why lithium is harder and lighter?
Lithium is not hard. It can be cut with a knife, as can all the common alkali metals in their pure metallic forms. Lithium is light mainly because it has a low atomic mass and low density.So it is harder and lighter dissimilar to other alkali metals in its group.
Can lithium be cut with a knife?
Metals, such as Lithium, Sodium and Potassium can be cut with a knife as they are very soft compared to other metals.
Is lithium softest among all alkali metals?
Potassium is the softest.
What does lithium do to a normal person?
Lithium helps reduce the severity and frequency of mania. It may also help relieve or prevent bipolar depression. Studies show that lithium can significantly reduce suicide risk. Lithium also helps prevent future manic and depressive episodes.
What is special about lithium?
Lithium is a special metal in many ways. It’s light and soft — so soft that it can be cut with a kitchen knife and so low in density that it floats on water. It’s also solid at a wide range of temperatures, with one of the lowest melting points of all metals and a high boiling point.
What is the softest alkali metal?
Lithium
Lithium is the softest alkali since it has less density than other metals.
What is the hardest alkali metal?
Lithium
Because of strong intermetallic bonding in Lithium, it is hardest as compared to other alkali metals.
Is lithium reactive or nonreactive?
Reactivity. Lithium is part of the Group 1 Alkali Metals, which are highly reactive and are never found in their pure form in nature. This is due to their electron configuration, in that they have a single valence electron (Figure 1) which is very easily given up in order to create bonds and form compounds.
Is lithium gas lighter than air?
Lithium is one of the lightest elements – lighter than oxygen – but is a solid.Lithium is not lighter than oxygen. It is, however, about half as dense as water.
Is lithium a hard metal?

Lithium Overview
| Chemical symbol | Li |
|---|---|
| Hardness | Very soft (0.6 on Mohs hardness scale, Talc = 1, Diamond = 10) |
| Melting point | 180.54°C (lithium has the highest specific heat capacity of any solid element) |
| Boiling point | 1,342°C |
| Electrical resistivity | 9.5mΩ cm – Very low resistivity, making Li an excellent conductor of electricity |
How strong is lithium?
The dose usually ranges from 600 mg to 1200 mg daily, but some people may require higher doses depending on weight or symptoms. Only your health care provider can determine the correct dose for you. Extended release tablets: Swallow the tablet whole. Do not crush or chew extended release tablets.
Can you get high on lithium?
Mood-stabilizing drugs like lithium are prescribed to treat bipolar disorder and other co-occurring disorders. Teens who misuse these drugs may find that not only does lithium not produce a high, but it’s also a toxic drug that can lead to dangerous side effects including death.
Is lithium good for anxiety?
Lithium improves the body’s ability to synthesize serotonin. This simply means that the body’s levels of serotonin increase in response to lithium, which has the effect of improving mood and reducing feelings of anxiousness.
