• May 04, 2017 · CHOOSE YOUR ATOMIC ORBITALS & AXES Carbon has 2s and 2p atomic valence orbitals. Oxygen has 2s and 2p atomic valence orbitals. ATOMIC ORBITAL ENERGY DIAGRAM From the original atomic orbital energies, we then construct the two atomic orbital energy diagrams: (On an exam, you may only be expected to work with homonuclear diatomic molecules, in ...
  • Explains what an atomic orbital is, and looks at the various kinds of atomic orbital - s, p, d and f. A customizable and printable periodic table of Lewis dot diagrams for drawing structures. The four common spdf orbital sets are presented as artistic representations in the following chart in typical, but...

  • The millions of different chemical compounds that make up everything on Earth are composed of 118 elements that bond together in different ways. This module explores two common types of chemical bonds: covalent and ionic. The module presents chemical bonding on a sliding scale from pure covalent to pure ionic, depending on differences in the electronegativity of the bonding atoms. Highlights ...
  • An orbital can hold 0, 1, or 2 electrons only, and if there are two electrons in the orbital, they must have opposite (paired) spins. When we draw electrons, we use up and down arrows. So, if an electron is paired up in a box, one arrow is up and the second must be down.
  • Molecular Orbital Theory. • Lewis dot structures, VSEPR theory, and valence bond theory all rely on atomic orbitals, and consequently fail to The energy diagram shows the energies involved in bonds of bonding and anti-bonding orbitals. The bonding levels for two unique 1s orbitals are equal and are...
  • Explain why an electron in the bonding molecular orbital in the H2molecule has a lower energy than an electron in the 1satomic orbital of either of the separated hydrogen atoms. 40. Predict the valence electron molecular orbital configurations for the following, and state whether they will be stable or unstable ions. (a)Na22+ (b) Mg22+ (c) Al22 ...
  • There are three atomic orbitals, so there must be three MO's. All of the atomic orbitals must be of the same phase in the lowest energy orbital, which produces an MO with two bonding interactions and no anti-bonding interactions. This orbital is a bonding orbital. The next highest orbital must contain one nodal plane placed in the center.

Schematic diagram of inner atomic electron shells. 2.2 Origin of Characteristic X-rays 'Characteristic' X-rays result from electron transitions between inner orbits, which are normally full. An electron must first be removed in order to create a vacancy into which another can 'fall' from an orbit further out.
We can do this for any element, BUT, we must use only noble gases in the brackets. I call this the noble gas simplification. In this method of writing electron configurations, the last noble gas before we get to the element of interest is the noble gas we put into the brackets.

In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atom's nucleus. All atoms have one or more electron shell(s), all of which have varying numbers of electrons. Each electron shell has one or more electron sub-shells, or sub-levels.
In this activity, students will create a periodic table using orbital rules from a planet called P-10 and identify periodic trends and bonding rules.
