The unique optomap ultra-widefield view helps your eye care practitioner detect early signs of retinal disease more effectively and efficiently than with traditional eye exams. Early detection means successful treatments can be administered and reduces the risk to your sight and health.
An electron dot diagram is a method of writing the chemical symbol of an element by surrounding it with dots to indicate the number of valence electrons. Valence electrons are found in an atom's outer shell and are the ones involved in chemical reactions.
Noble Gas Notation. Uses the symbol for the previous noble gas and then adds the additional electron configuration notation for the series of elements up to the next noble gas. For example, the electron notation of carbon is 1s22s22p2, and the noble gas notation is [He]2s22p2. This notation makes it easier to identify elements, and is shorter than writing out the full notation of atomic orbitals.
