Figure \(\PageIndex{2}\): Water is a polar molecule, as greater electron density is found around the more electronegative oxygen atom. Polar molecules attract one another by dipole-dipole forces, as the positive end of one molecule is attracted to the negative end of the nearby molecule.
30 Αυγ 2018 · This is a collection of the electron shell diagrams of all 118 elements. Each element’s atom is shown with the number of protons in the nucleus with shells of electrons filled by energy levels. The lowest energy level is closest to the nucleus.
14 Αυγ 2020 · Electron configurations and orbital diagrams can be determined by applying the Pauli exclusion principle (no two electrons can have the same set of four quantum numbers) and Hund’s rule (whenever possible, electrons retain unpaired spins in degenerate orbitals).
12 Σεπ 2022 · Example \(\PageIndex{2}\): M olecular Orbital Diagrams, Bond Order, and Number of Unpaired Electrons. Draw the molecular orbital diagram for the oxygen molecule, O 2. From this diagram, calculate the bond order for O 2. How does this diagram account for the paramagnetism of O 2?
Shells, subshells, and orbitals. Introduction to electron configurations. The Aufbau principle. Valence electrons. Electron configurations of ions. Electron configurations of the 3d transition metals. Atomic structure and electron configuration.
Interactive periodic table showing names, electrons, and oxidation states. Visualize trends, 3D orbitals, isotopes, and mix compounds. Fully descriptive writeups.
The Bohr model shows the atom as a central nucleus containing protons and neutrons, with the electrons in circular electron shells at specific distances from the nucleus, similar to planets orbiting around the sun.
