We use electron configuration for atoms or ions. You can't use it for compounds.
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
The electron configuration for V3 is Ar 3d2.
The electron configuration of V3 is Ar 3d2.
The electron configuration of curium is [Rn]5f7.6d1.7s2.
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
A cation has a depleted electron configuration.
The electron configuration for beryllium, Be, is 1s22s2.
The electronic configuration of einsteinium is: [Rn]5f11.7s2.
Hydrogen electron configuration will be 1s1.
The electron configuration of francium is [Rn]7s1.
Sulfur must lose six electrons to attain noble gas electron configuration (in SO3, H2SO4 etc) but in most of the compounds it will exist as sulphides which is formed when sulphur will gain two electrons.
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
Uranium electron configuration: [Rn]5f36d17s2
The electron configuration of beryllium is 1s2 2s2.
The electron configuration for germanium is [Ar]3d10.4s2.4p2.
The electron configuration of boron is [He]2s2.2p1.
