1 DO create a list of questions (to keep handy when your Trainee calls) regarding questions about BMT and mail! The call can come at any time and may be short, so plan accordingly!  DO give your Traineeâs address to loved ones, friends and family who you trust will follow the rules while writing your Trainee.
3.1 Atomic and Molecular Orbitals. We can use molecular orbital (MO) theory to describe the structure of molecules in more detail. MO theory also provides a means of predicting the shapes of molecules. In MO theory, our first. hypothesis is that bonding occurs by the overlap of singly occupied atomic orbitals. So if we.
No matter what its shape, an orbital can only hold a maximum of two electrons at any time. At the lowest energy level, the one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals; a 2s, 2p1, 2p2, and a 2p3. Each of these orbitals can hold 2 electrons, so a total of 8 electrons can be found at this level of energy. In larger and larger atoms, electrons can be found at higher and higher energy levels (e.g. 3s and 3p).
