Are friend making a design of one atom and need to know just how to place the electrons roughly the nucleus? If so, friend will must know just how to read an element"s electron construction table. Monitor these easy directions to learn how!
What is one electron configuration table?
An electron configuration table is a kind of code that defines how countless electrons space in each power level of an atom and how the electrons are arranged within each power level. It package a many of information into a small space and also it bring away a tiny practice come read. Because that example, this is the electron construction table because that gold:
What perform all those numbers and also letters mean?
Each row of one electron configuration table is kind of choose a sentence. Each "sentence" is made up of smaller "words". Every "word" adheres to this format:
The an initial number is the energy level. We have the right to tell appropriate away that an atom that gold includes 6 energy levels.
You are watching: In an electron configuration what does a superscript stand for
The lowercase letter is the sub-shell. The sub-shells are named s, p, d and f. The variety of available sub-shells rises as the energy level increases. Because that example, the an initial energy level only has an ssub-shell when the 2nd energy level consists of both one ssub-shell and a psub-shell.
The number in superscript is the number of electron in a sub-shell. Every sub-shell can hold just a certain variety of electrons. The ssub-shell deserve to hold no an ext than 2 electrons, the psub-shell have the right to hold 6, the dsub-shell have the right to hold 10 and also the fsub-shell have the right to hold as countless as 14.

How deserve to I use the electron construction table to tell me...
How plenty of energy level does an atom have?
Since the electron construction table perform each energy level by row, you have the right to tell how numerous energy levels there room by seeing how numerous rows there are. Together was pointed out earlier, an atom of gold includes six energy levels, as presented below:
How countless electrons room in each power level?
The total variety of electrons in an energy level is the sum of the electrons in each sub-shell the that power level. Just include the number in superscript with each other to discover the number of electrons in an energy level. The number of electrons in each power level in an atom of yellow is displayed below:
How plenty of electrons room in an atom"s outer power level?
This is simply a mix of the previous two examples. Usage the electron construction to find that atom"s highest power level and then include up the numbers in superscript to discover the variety of electrons that space in it. Over there is one electron in the outer power level of one atom of gold, as shown below:
