In NaCl, there exists Na+ and Cl- ions and with the electron configuration of [He]2s22p6 (for Na+) and [Ne]3s23p6 (for Cl-)
One electron is transferred from sodium to chlorine in the ionic bond between sodium and chlorine in NaCl. Sodium loses one electron to achieve a stable electron configuration with a full outer shell, becoming a positively charged ion (Na+), while chlorine gains this electron to achieve a stable electron configuration, becoming a negatively charged ion (Cl-).
The electron configuration for oxygen is 1s2 2s2 2p4. The electron configuration for sulfur is 1s2 2s2 2p6 3s2 3p4.
The electron configuration for beryllium, Be, is 1s22s2.
A cation has a depleted electron configuration.
The long form of the electron configuration of einsteinium (Es) is [Rn] 5f11 7s2.
The electron configuration of francium is [Rn]7s1.
The electron configuration of hydrogen is 1s1, indicating that it has one electron in its 1s orbital.
The electron configuration of boron is [He]2s2.2p1.
The electron configuration of beryllium is 1s2 2s2.
Uranium electron configuration: [Rn]5f36d17s2
The electron configuration for germanium is [Ar]3d10.4s2.4p2.
