The periodic table is an incredibly helpful tool in writing electron configurations. Using the periodic table to determine the electron configurations of atoms is key, but also keep in mind that there are certain rules to follow when assigning electrons to different orbitals. The s-block is the region of the alkali metals including helium (Groups 1 & 2), the d-block are the transition metals (Groups 3 to 12), the p-block are the main group elements from Groups 13 to 18, and the f-block are the lanthanides and actinides series. Each orbital can be represented by specific blocks on the periodic table. The 1s orbital and 2s orbital both have the characteristics of an s orbital (radial nodes, spherical volume probabilities, can only hold two electrons, etc.) but, as they are found in different energy levels, they occupy different spaces around the nucleus. Orbitals on different energy levels are similar to each other, but they occupy different areas in space. The energy level is determined by the period and the number of electrons is given by the atomic number of the element. The p, d, and f orbitals have different sublevels, thus can hold more electrons.Īs stated, the electron configuration of each element is unique to its position on the periodic table. The four different types of orbitals (s,p,d, and f) have different shapes, and one orbital can hold a maximum of two electrons. Electrons exhibit a negative charge and are found around the nucleus of the atom in electron orbitals, defined as the volume of space in which the electron can be found within 95% probability. Every element on the Periodic Table consists of atoms, which are composed of protons, neutrons, and electrons. : Fixed note about gas density to read ".\)īefore assigning the electrons of an atom into orbitals, one must become familiar with the basic concepts of electron configurations. : Updated the Excel and PDF files to correctly classify Radon as a gas.
: Update (Version 1.1) - Added indicator for radioactive elements, color-coded melting and boiling point data, added the crystal structure (in place of the van der Waals radius), and marked the atomic radius as either the metallic radius (m) or covalent radius (v). Tip: You can create your own mini periodic table poster by printing on 11x17 paper. You can use this data table for creating trend charts or use lookup functions to use the data within calculations. If you'd like to create your own personal custom periodic table, you can download this Excel file and add your own sets of properties.ĭata: The spreadsheet also includes a worksheet that lists the property data for the elements. This spreadsheet was used to create the printable periodic table above and also contains a worksheet listing the data for various chemical properties.
