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 wil

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 ...
What is electron configuration? Learn how to do electron configuration. See the relationship between electron configuration and the energy levels...
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...
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 ...

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, ...
There are four ways to represent an electron configuration.1. The Orbital (Box) Diagram These show each orbital as a box. The boxes are filled with arrows (representing electrons). The electrons are paired with opposite spin (one arrow pointing up, one arrow pointing down). Example For ...
elements. The electronic configuration is the electronic structure of the atoms; the specific levels, sublevels, and number of electrons occupying orbitals for a given atom. Let’s look at group 1A elements. Hydrogen has 1 electron, and the electronic ...
