In atomic physics and quantum chemistry, the Aufbau principle (/ ˈ aʊ f b aʊ /, from German: Aufbauprinzip, lit. 'building-up principle'), also called the Aufbau rule, states that in the ground state of an atom or ion, electrons first fill subshells of the lowest available energy, then fill subshells of higher energy. For example, the 1s ...
The σ from the 2p is more non-bonding due to mixing, and same with the 2s σ. This also causes a large jump in energy in the 2p σ* orbital. The bond order of diatomic nitrogen is three, and it is a diamagnetic molecule. [12] The bond order for dinitrogen (1σ g 2 1σ u 2 2σ g 2 2σ u 2 1π u 4 3σ g 2) is three because two electrons are now ...
The approximate order of filling of atomic orbitals, following the arrows from 1s to 7p. (After 7p the order includes subshells outside the range of the diagram, starting with 8s.) The principle works very well (for the ground states of the atoms) for the known 118 elements, although it is sometimes slightly wrong. The modern form of the aufbau ...
They are similar to "store brand" or "private label" products sold under a brand particular to the merchant, but typically priced lower and perceived as lower quality. The term off brand is sometimes used. In the United Kingdom, these products are often referred to as "own brand" items.

Configuration items are represented by their properties. These properties can be common to all the configuration items (e.g. unique item code that we will generate, description of function, end of the lifecycle or business owner that is approving configuration item changes and technical owner, i.e. administrator, that is supporting it and implementing the changes).
The label must show the model number, the size, key features, and display largely a graph showing the annual operating cost in range with similar models, and the estimated yearly energy cost. [ 2 ] [ 3 ]
