OpenScience is a community effort by students to bring conceptual explanation and detailed information about various topics in the various fields of science. Students will share their knowledge, research, and ideas about scientific discoveries and the workings of nature as we know it. This wiki will have sections for broader science areas like biology, chemistry, and physics, which will be stubdivided by concept/topic groups. The goal of this wiki is not only to be a repository of scientific knowledge, but also to provide explanations and even lessons such that students can learn about interesting topics outside of the classroom in a way that is coherent and understandable.

Lithium is the third element in the periodic table according to its atomic number 3. It is a soft metal belonging to the alkali metal group. Lithium is highly reactive due to its monovalency(+1) and also very flammable.
Due to high reactivity, lithium never occurs in its free state form but instead exists in form of compounds which are usually ionic but can also be sometimes covalent. An interesting thing to note about lithium is that it has a very low density due to which it floats in water. Read More>>>
On the right hand side is the crossword puzzle. There are elements from the periodic table which are spread in all the directions(horizontal, vertical and diagonal). The answer for this puzzle is hidden on our wiki if you dare then try to search the wiki for the answers: it's not so hard though.
We prefer that you open the full sized image as it would be more easy to view.
The poles on Uranus are warmer than the equator because its axis is tilted quite heavily!
Above 4 °C, water expands when heated and contracts when cooled. But between 4 °C and 0 °C it does the opposite, contracting when heated and expanding when cooled. Stronger hydrogen and oxygen bonds are formed as the water crystallizes into ice. By the time it's frozen it takes up around 9% more space.
