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.

An ionic compound is composed of an anion and cation whose charges together must be neutral. When naming an ionic compound, we must determine the names of the anion and cation that have bonded. Given the formula, we determine the elements (or polyatomic ions) that make up the compound in question. We then write the anion name after that of the cation, and we have the formula.Learn More>>>
