Covalent bonds | Molecular and ionic compound structure and properties | AP Chemistry | Khan Academy

Covalent bonds involve the sharing of electron pairs between atoms. Electron pairs shared between atoms of equal or very similar electronegativity constitute a nonpolar covalent bond (e.g., H–H or C–H), while electrons shared between atoms of unequal electronegativity constitute a polar covalent bond (e.g., H–O).

Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!

Honestly this Classes are more intresting than my School. In School teaching is Boring but in this its way more intresting. A Big Thank you

0:17 Covalent Bonds *Share* Electrons
1:21 The 2 Oxygens want 8 electrons
2:32 This sharing of electrons forms a covalent bond
3:30 H20, a water molecule

So does this mean i will get my big mac

Please make a video about coordinate covalent bond

I would like to add that in determining whether you need a triple bond, double bond, or single bond, you just have to figure out the number of pairs of electrons you need, so for instance in carbon(2)~dicarbon, you will need a triple bond, with two electrons (Valence electrons) left on each carbon atom because if you count the number of pairs of electrons if we only used a double bond we would have used more pairs of valence electrons then we have, and same goes for a single bond. So just always check you have the correct number of pairs of electrons. In this case dicarbon is unstable, as you can see that we would have incomplete s and p subshells, but the point is always make sure your pairs match up with the number of electrons.

@khanacademy I don't understand why Hydrogen didn't just want to lost its electron, like Na wanted to lose it to give to Cl? What made Hydrogren share it, rather than give it away and become ionically bonded?

I don’t why u would need too know this in unless ur going too be a scientist of some sort

[pk-zdpy]

but what if there are more than 2 types of atoms(like HCN), which one is going to be in the middle?

Sorry about that. My little brother was being annoying.
