Lithium has seven isotopes of which two are stable. It was named by Johann Arfvedson (who also discovered it). Examples of solid elements are sodium, carbon, aluminium. Lithium comes from the Greek word "lithos" meaning "stone" or "rock". Most elements are solids, only 11 are gases and 6 are liquid.
Adding thermal energy to a system of particles increases the average kinetic energy. Each state has a different particle arrangement, which allows particles to move (or not move), and sometimes this particle arrangement can change, altering the state of matter. are found in any given atom, the Periodic Table of the Elements is the place to find out. It was isolated in its pure form a year later by English chemist Humphry Davy. Matter comes in three states: solid, liquid or gas. Matter is found in 3 major states solid, liquid and gas. Lithium was first detected as an element by Swedish chemist Johann August Arfvedson in 1817 when he was analyzing petalite ore. Other applications include lubricating greases, high performance aircraft materials, and anti-depression drugs. Another major application is in the manufacture of ceramics and glass. Around 27% of lithium used for industry is used in batteries. Probably the one you are most familiar with is lithium batteries. Lithium is used in a variety of applications. However, it is found throughout the world in a variety of areas including seawater, mineral springs, and igneous rocks. However, it is less reactive and explosive than the other alkali metals.īecause it is so reactive, lithium is not found in its pure form in nature. It is flammable and can even explode when exposed to air and water. Lithium's single valence electron allows it to be a good conductor of electricity. It can cause burns if it comes into contact with the skin. It needs to be stored in mineral oil as it will react with air or water. It has the highest specific heat capacity of any solid element. It is the least dense of the solid elements and is the lightest of all the metals. Like all alkali metals it has a single valence electron that it readily gives up to form a cation or compound.Īt room temperature lithium is a soft metal that is silvery-white in color. Lithium is part of the alkali metal group and can be found in the first column of the periodic table right below hydrogen.

It's a more productive way, in my view, to build a functional memory of the elements. Check out our interactive series of lesson plans, worksheets, PowerPoints and assessment tools today All teacher-made, aligned with the Australian Curriculum. Before long you'll assimilate a lot more elements into your long-term memory and what gets stored there will make some logical sense.įor example, all of the noble gas elements (under He) are much more similar than different. If you know these elements, then you've got a framework on which to build a memory of the other elements in the group as you study chemistry. These are the elements at the top of each column (group), and they are generally representative of the other elements in the group. I ask my students to memorize the first ten elements of the table: H, He, Li, Be, B, C, N, O, F and Ne. Your chemistry teacher might disagree with me, so be careful here, but my view is this:
