Witryna8: octa. 9: nona. 10: deca. The above list shows the 10 most basic chemistry prefixes for naming compounds, which come from Greek. These prefixes can be used to name just about any compound. With a little bit of practice, naming compounds will become easier and easier! Don’t get frustrated with yourself if you don’t understand it right away. An octatomic element is a chemical element that, when standard conditions for temperature and pressure is stable, is in a configuration of eight atoms grouped together. The canonical example is sulfur, S8, but red selenium is also an octatomic element stable at room temperature. Octaoxygen is also known, but it is extremely unstable. lighting shops in weymouth
