These are s-elements, with group 1 having ns1 and group 2 having ns2 configuration of outermost electrons. The first period has only H and He because with n=1 only s-orbitals are available. The second period will have six more elements, p-block (groups 13–18) elements that will have ...

What is electron configuration? Learn how to do electron configuration. See the relationship between electron configuration and the energy levels...
Electron configuration is a shorthand notation for describing the arrangement of the electrons about the nucleus. General Format using the quantum numbers: n l e- RULES: 1. Fill the lowest energy levels first. 1s 2s 2p 3s 3p 4s 3d 4p ...
To write a complete electron configuration for an uncharged atom, Determine the number of electrons in the atom from its atomic number. (See Below.) Add electrons to the sublevels in the correct order of filling. Add two electrons to each s sublevel, 6 to each p sublevel, 10 to each ...

The last electron written for the electron configuration for an element in columns 13 - 18 is in the p-orbital, so that is the p-block. The bottom two rows that are not connected to the rest of the periodic table have electrons in the f-orbital, so they are the f-block. What is...
NowI’ll try to explain the notation for electron configurations to you. The arrangement of the electrons among the various orbitals of an atom is called the electron configuration of the atom. Electron configurations can be written using a special notation that tells the principal energy level, ...
Electron Configurations Electron configuration = a description of which orbitals contain electrons for a particular atom. Finding Electron Configuration The complete list of orbitals and the order in which they fill for all of the currently discovered elements is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, ...
Chapter 5: Electron Configuration, Lewis Dot Structure, and Molecular Shape Electron configuration. The outermost electrons surrounding an atom (the valence electrons) are responsible for the number and type of bonds that a given atom can form with other ...
