Get Electron Configuration Worksheet

Count orbital sets up to your atom. Write down the column-blocks beginning with the column number followed by the block symbol, like this: 1s 2s 2p 3s 3p 3d 4s 4p 4d 4f 5s 5p 6s (in case of Erbium). Note: The above electron configuration of Er is written in the order of ascending shell numbers.

Follow the steps below to write short cut version of electron configurations. Step 1: Find the element on the periodic table. Step 2: Go back to the last noble gas that was passed (atomic number). Step 3: Write the symbol of the noble gas in brackets to start your electron configuration.

This is a memory aid that everyone that has ever taken general chemistry has seen. Follow the diagonals sequential, from tail to head. Remember that s gets two electrons, p gets six electrons, d gets 10 electrons, and f gets 14 electrons.

Therefore, the electronic configuration of sulfur can be written as 1s2 2s2 2p6 3s2 3p4.

1:25 7:22 Which is 1 s 2. So we have 1 s 2 next. We are on the second row but still in the S block. So 2 s 1 2MoreWhich is 1 s 2. So we have 1 s 2 next. We are on the second row but still in the S block. So 2 s 1 2 2 s 2 and we stop since we reach the element we wanted.

We build electron configurations by filling the lowest energy orbitals first then filling progressively higher energy orbitals. This is known as the aufbau principal. So we fill subshells in the order 1s 2s 2p because 1s is the lowest energy, 2s is higher energy, and 2p is highest energy.

How To write an electron configuration Determine the total number of electrons to be represented. Use the Aufbau process to fill the orbitals with electrons. The Aufbau process requires that electrons fill the lowest energy orbitals first. ... The sum of the superscripts should equal the total number of electrons.
