1s22s22p3. Adding the exponents gives a sum of 7, which is the total number of electrons a C- ion has. Follow a diagonal rule chart and they should become easy.
The element with this electron configuration is carbon (C). This electron configuration corresponds to 6 electrons, which is the atomic number of carbon.
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.
B. Rn6s25d1. Lanthanum (La) has an atomic number of 57, so the electron configuration would be [Xe] 6s25d1. The noble gas right before La on the periodic table is Radon (Rn), hence the correct electron configuration for lanthanum is Rn6s25d1.
The electron configuration for V3 is Ar 3d2.
The element with this electron configuration is carbon (C). This electron configuration corresponds to 6 electrons, which is the atomic number of carbon.
The long form electron configuration for carbon is simply 1s2 2s2 2p2. The noble gas shortcut electron configuration for C is [He] 2s2 2p2.
the electron configuration of phosphorous is 1s2, 2s2, 2p6, 3s2, 3p3. Your welcome! -Bri .C.
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 carbon in noble gas notation is [He] 2s^2 2p^2. This notation indicates that carbon has the same electron configuration as helium up to the 1s orbital, followed by the electron configuration of the remaining orbitals (2s^2 2p^2).
The electron configuration of francium is [Rn]7s1.
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
