Configuration Definition and 268 Threads

Configuration management (CM) is a systems engineering process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life.
The CM process is widely used by military engineering organizations to manage changes throughout the system lifecycle of complex systems, such as weapon systems, military vehicles, and information systems. Outside the military, the CM process is also used with IT service management as defined by ITIL, and with other domain models in the civil engineering and other industrial engineering segments such as roads, bridges, canals, dams, and buildings.

    NYC Chemistry Regents Electron Configuration

    Well, I have to find the electron configuration of ions. Relatively simple. But since I don't know how to do it, it's hard. I've seen some past chemistry regents electron configurations and that's too complicated for me. I'm talking about e.c. like 2-8-2. That sort of electron configuration. I...

    Exploring Energy Levels and Electron Configurations in Atomic Models

    Hello, why in the normal atomic configuration every layer except the second can contain only up to 8 electrons if for example the level with quantic number 3 contain up to 18 electrons? What relation is there between this two models? Thank you!

    Why doesn;t Carbon show deviation from electron configuration

    We all know that carbon shows the configuration 1s2- 2s2- 2p2 But, since half-filled and fully filled orbitals are more stable, why doesn't it show the configuration 1s2- 2s1- 2p3 ? Why doesn't the 2s orbital give 1 electron to 2p, as in the case of Chromium, where one electron goes from 3d to...

    Reaching any point mass configuration by internal forces

    If we have N unique point masses, is it possible to use only internal forces (i.e. forces between each pair of masses) to reach any configuration of the points (modulo rotations and translations)?

    Electron Configuration: Understanding and Calculating

    A quick question... When you have to decide the electron configuration for an atom you find the number of electrons in the shell as 2n^2 and the subshell by 2(2l+1). If I'm not mistaken "the shell" is the total electrons in an atom, right ? So for n = 1 it makes sense that there can be a...
