Beryllium
Iron (Fe)
The element that forms an ion with an electronic configuration of Ar with a -2 charge is oxygen (O). When oxygen gains two electrons, it achieves a stable electron configuration similar to argon.
The element with an ns2np5 type electronic configuration in its outermost shell is fluorine (F). It has a configuration of 1s2 2s2 2p5.
The electron configuration of cobalt is [Ar]3d7.4s2.
Silicon. Electronic configuration [Ne]3s23p2
A stable electronic configuration refers to having completely filled valence electron shells or half-filled subshells, leading to lower energy levels and enhanced stability. Conversely, an unstable electronic configuration consists of partially filled outer electron shells or incomplete subshells, which tend to be more reactive and seek to attain a stable configuration through chemical bonding or electron transfer.
The element is Argon. Its configuration is 2 8 8.
definition of electronic configuration
The element with the electron configuration 6s^2 5d^1 4f^1 is lawrencium (Lr), with atomic number 103. It is a synthetic element that is radioactive and not found naturally on Earth.
the element is tungsten with the electronic configuration Xe 4f14 5d4 6s2
Iron (Fe)
The element chlorine does not have noble gas configuration. But chloride ion formed (when chlorine accepts an electron) has noble gas configuration of argon.
It is the electron configuration of a neutral, not excited atom.
