How do you write the electron configuration for all elements?
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.

How do you calculate electron configuration?
To calculate an electron configuration,
divide the periodic table into sections to represent the atomic orbitals
, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.
What are the three rules for writing the electron configuration of elements?
electron configuration
When assigning electrons to orbitals, we must follow a set of three rules:
the Aufbau Principle, the Pauli-Exclusion Principle, and Hund’s Rule.
What is the full electron configuration?
The electron configuration is the standard notation used to describe the electronic structure of an atom. Under the orbital approximation, we let each electron occupy an orbital, which can be solved by a single wavefunction. … These numbers can be thought of as an electron’s “address” in the atom.
What is 1s 2s 2p 3s 3p?
In the question 1s 2s 2p 3s 3p represents
electron orbital energy levels
. These orbital energy levels depend on 2 quantum numbers-Principal quantum number (n) and Azimuthal quantum number(l) . … The sequence of orbital energy levels is as always-1s < 2s = 2p < 3s = 3p = 3d <4s = 4p = 4d= 4f.
What is the valency of oxygen?
The valency of oxygen is
2
, because it needs two atoms of hydrogen to form water.
