Good morning students!

Good morning sir..

yes, when I was young

Did you ever had a crush on someone?

not yet

Have you felt that feeling when there's something that's attracting you to go near her?

Yes, always.

why are you asking us this today sir?

Because, it is related to our lesson for today. It's electronegativity

Sir, what is electronegativity?

Electronegativity is a chemical property that describes the tendency of an atom or a functional group to attract electrons towards itself.

Now I know how my feelings towards my crush back in the days is connected to our lesson

me too! Because you get attracted to your crush and electronegativity describes the tendency of an atom to attract electrons

That's great! Now you guys know what electronegativity is.

it's because one of the elements has a higher electronegativity than the other.

why are they not shared equally?

aha! just like the shared pair of electrons between an atom of hydrogen and an atom of bromine, it is not shared equally.

Yes, that's right! Now it seems like both of you understand what our lesson for today is. Do you have furthermore questions?.

no sir.

because our topic is somehow related to this.

what is our topic for today sir?

it's about polarity of covalent bonds.

what is polarity of covalent bonds and how is this related about not being shared equally sir?

A polar covalent bond is a bond formed when a shared pair of electrons are not shared equally.

Hi class, welcome back! are you ready for our lesson?

yes sir !!

Do you have a big brother or sister?

I have a older brother sir

me too

do you notice that your parts when it comes to things aren't shared equally?.

yes sir, why?

Then that's it for today, see you again next time class.
