In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital. The remaining four electrons will go in the 2p orbital. Therefore the O electron configuration will be 1s22s22p4.
Which element has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d6?
Thus, following the rules on how to fill the orbitals, the electronic configuration of iron (for example) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 , and it is abbreviated form [Ar] 4s2 3d6.
What is the electron configuration of the oxide ion 02 -)?
Explanation: For oxygen, Z=8, and thus O2− has a configuration of: 1s22s22p6, i.e. 10 electrons distributed.
How do you write the electron configuration?
Writing Electron Configurations. When writing an electron configuration, first write the energy level (the period), then the subshell to be filled and the superscript, which is the number of electrons in that subshell. The total number of electrons is the atomic number, Z.
What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d3?
Example: 1s2 2s2 2p6 3s2 3p6 4s2 3d3 (This has a total of 23 electrons which equals the atomic number of V – Vanadium.)

What element has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 and which block is it in?
1 Answer. Stefan V. If you are referring to a neutral atom, then Vanadium (V) has that particular electron configuration. This means that the atom you’re looking for has an atomic mass of 23, which corresponds to the atomic mass of Vanadium, a transition metal located in the fourth row, group 5 of the periodic table.
What is 1s 2s 2p 3s 3p?
1s 2s 2p 3s 3p represents the electron orbital energy levels.
Which element has the electron configuration 2 8 7?
⇒ 2+8+7 = 17. Therefore, the atomic number of this element is 17 and the element is chlorine.
What is S and P mixing?
s-p mixing occurs when the s and p orbitals have similar energies. When a single p orbital contains a pair of electrons, the act of pairing the electrons raises the energy of the orbital. Thus the 2p orbitals for O, F, and Ne are higher in energy than the 2p orbitals for Li, Be, B, C, and N.
How many valence e are in B2?
For example, B2 has 3 + 3 = 6 valence electrons.
How many electrons does B2 2 have?
We have three valence electrons from each B atom, so B₂ will have six valence electrons.
