How can helium exist in three different forms
Web24 de mar. de 2024 · Matter typically exists in one of three states: solid, liquid, or gas. Figure 2.3. 1: Matter is usually classified into three classical states, with plasma sometimes added as a fourth state. From left to right: quartz (solid), water (liquid), nitrogen dioxide (gas). The state a given substance exhibits is also a physical property. WebLithium is rare in the Universe, although it was one of the three elements, along with hydrogen and helium, to be created in the Big Bang. The element was discovered on Earth in 1817 by Johan August Arfvedson (1792-1841) in Stockholm when he investigated petalite, one of the first lithium minerals to be discovered.
