First 54 elements

Atoms are defined as the simplest form of an element. They make up everything we see and each atom has their own characteristics.

Using the details of any element, we can draw its atomic structure, however it is easier if we can figure out its electronic configuration beforehand. Remember, the max electrons in every shell is in this order : 2.8.8 or 2.8.18, which can be calculated using the formula 2n².
