Electron Configuration for the First Twenty Elements - Made Simple

A detailed explanation of how to use the Periodic Table to write the electron configurations for the first twenty elements on the Periodic Table (Hydrogen through Calcium).

Using the pattern of orbital blocks, we'll write the electron configurations. Before we can write the electron configs, we first need to know the number of electrons for the each atom. When we write the configuration we'll put these electrons in orbitals around the nucleus of the atom.

Helpful videos:

Electron configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.
Using the Periodic Table we can quickly write the electron configurations for the first 20 elements (H through Ca).

Actually man....I didn't understand that was taught in my school..But yours is very very easy to understand...Keep it up man!

You definitely helped me pass my first semester of chemistry, thank you 🫀

[yashsethi]

Thank you so my science exam is just around the corner and i needed just this

[simarvlogs]

It's very helpful thank you sir🌹🌹

sir, you explained this topic like no one else my teachers just told me that 1s would that only 2 electrons and thats it

You made chemistry my favourite subject

Thank you for this video....it really understand it clearly.... thank you so much 😊😊

Sir, lets say you have acetone, would you just add up the carbon and oxygen electrons to calculate the total electron count? Otherwise, how else would you be able to calculate the total electron count for acetone?

Hi Dr Wayne, hope you're doing good. I have a question for you, if you don't mind of course.

Let's say we're looking at an acetylene molecule. So there’s an sp hybridization . Is it possible for one of the p orbitals that remain unhybridized have its axis oriented towards the bond with the other carbon atom ? I believe that way we could get two sigma bonds and one pi bond. This said I know this is impossible so the question would be what is it about the unhybridized orbitals that orients them 90° from the axis in which the sigma bond is made?

Thank you,
Yanis

Sir, it would be so helpful if you add up to exothermic reaction and endothermic reaction ( irreversible reaction, reversible reaction, it's equation) that kinda stuffs, you know what I mean??

It would be so much helpful if you do it, so.. pls sir..
