Electron Distributions Into Shells for the First Three Periods. A chemical element is identified by the number of protons in its nucleus, and it must collect an equal number of electrons if it is to be electrically neutral.
Orbital, in chemistry and physics, a mathematical expression, called a wave function, that describes properties characteristic of no more than two electrons in the vicinity of an atomic nucleus or of a system of nuclei as in a molecule.
Orbital Diagrams PLAN: Identify the electron of interest and note its level (n), sublevel, (l), orbital (m l) and spin (m s). Count the electrons in the order in which they are placed in the diagram. PROBLEM: Write a set of quantum numbers for the third electron and a set for the eighth electron of the F atom. SOLUTION: F (Z = 9) 1s22s22p3
The table below contains some of the instrument abbreviations used in conjunction with P&ID symbols in instrumentation diagrams. I have dealt with some of them before but for the purpose of emphasis and completeness let us go through again. The list here is by no means exhaustive but it is a good starting point for beginners to P&IDs:

You can optionally display the orbits of the planets as well as the selected small-body, zoom in/out, rotate the diagram, and animate the small-body's motion over time. In addition, there are diagrams showing the distribution of orbital elements for most known inner solar system asteroids and comets.
Here we have a molecular orbital diagram for the CO molecule. So again, it's drawn in the familiar pattern. You have the, here on this side you would have the energy, so the energy is going up there. So you have the carbon two S orbital, and you have the carbon two P orbitals.
LCAO MO Energy Diagram for H2 Energy H-H ∆E1 ∆E2 • ∆E2> ∆E1, so the antibonding orbital is always more anti-bonding than the bonding orbital is bonding H2molecule: two 1s atomic orbitals combine to make one bonding and one antibonding molecular orbital. Ha Hb
