When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.
For the first electron around the nucleus, the effective nuclear charge equals the nuclear charge: Z_\text {eff} = Z Z eff = Z. The value of Z_\text {eff} Z eff then decreases approaching 1 1 for an infinite distance from the nucleus. This is the value of the potential energy experienced by the last electron added to the shell Remember that it

Electron Configurations are an organized means of documenting the placement of electrons based upon the energy levels and orbitals groupings of the periodic table. The electron configuration for the first 10 elements. H #1s^1# He #1s^2# Li #1s^2 2s^1# Be #1s^2 2s^2# B #1s^2 2s^2 2p^1# C #1s^2 2s^2 2p^2# N #1s^2 2s^2 2p^3# O #1s^2 2s^2 2p^4#
Wikipedia. The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons. Only the s and p electrons are involved in the octet rule, making it
This video shows you how to write the ground state electron configuration using noble gas notation (abbreviation) for the elements fluorine, sulfur and cadmium. This is the shortcut or shorthand method of writing the electron configuration for elements.
