Please type your answer as simple and understandable as you possibly can. Please give me at least 3 examples of finding the electric configuration from 3 elements. Thanks!

It is electRONIC configuration, and it means how the electrons in an atom are arranged in atomic orbits.
In an atom, electrons go into shell called principle quantum shells. These shells are split into orbits., referred to as s, p d, f, g, h and so on,
Electrons go in each separate orbit of each quantum shells. Once all the orbits within a shell are filled then the electrons begin to pair up.
The first shell is known by its quantum number 1 and it has only 1 orbit called s-orbit. This orbit can accept only 2 electrons.
The second shell is know by its quantum number 2 and it has 2 orbits called s- and p-orbit. As before, s-orbit can only accept 2 electrons but p-orbit can accept 6 electrons.
The third shell (known by number 3) has 3 types of orbits s-, p- and d- orbits. As before, s-orbit can hold 2 electrons, p- 6 electron and now d-orbit can hold up to 10 electrons.
So consider Na atom which has 11 electrons. These electrons will be arranged in Na atom as...
1s2 2s2 2p6 3s1
Consider Al which has 13 electrons. They are arranged as
1s2 2s2 2p6 3s2 2p1
Consider now Ti with 22 electrons.
1s2 2s2 2p6 3s2 3p6 3d2 4s2
The notation used is
Quantum shell no, orbit type, no. electrons.
Hope this makes some sense!

Electrons exist in orbitals. Since negatively charged particles repel each other, they can't be too close, so they have to expand on further from the nucleus. (8 electrons usually fill an orbital, hence an "octet".)
Electron configurations can be determined by looking at a periodic table, columns 1 and 2 are "s", rows 13-18 are "p", transition metals are "d" and the lactinides/actinindes at the bottom of a period table are "f.
This site can give a more in depth explanation, and if you scroll down you'll find a list of the electron configurations of all the elements! Which can speed things up quite a bit, and show you how they should look like and illustrate patterns.

This is an origami periodic table that might help you be able visualize orbitals.
