Worked example: Identifying an element from successive ionization energies | Khan Academy

Keep going! Check out the next lesson and practice what you’re learning:

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!

Much better explained than my chem professor bothered to get into. There are so so many bad chem teachers it should be a crime.

Awwwwn....thank you so much, I was almost crying I didn't get this topic😪🙏🏼🙏🏼

How would you use this chart to determine which period the element is in if you're not given the period of the element in the question?


If you're given the full list of ionisation energies for an element, would you just count how many big jumps there are until you reach that last ionisation energy level? Or would you count how many ionisation energy values there are in between the first and second big jump to figure out the maximum number of electrons held in that energy level? (for example, if there are 18 ionisation energy values given between the first and second big jump, you know that the energy level which can hold a maximum of 18 electrons is the 3rd energy level. Hence, the element is in the 4th period?)

Wow This was very helpful for me Thanks Sir May God bless you 🙏❣️✝️

[abisai]

how would you not confuse the first one for a valence electron though? Since it's still smaller than the next two how can we make sure?

THANKS YOU SO MUCH you saved me a whole question in my chemistry test hopefully i got A

[bigpeterzero]

Khan god bless you I have been asking everyone and didn't understand anything about Ionisation energy but now you made me understand it. Love from Sweden pal.

[negar]

Thank you so much. saving me in my finals!

[parthkadam]

My chem teacher didn't even bother to explain what IE even means. Thanks Khan Academy.

[shekkrf]

Thank you🙇‍♀️🙇‍♀️🙇‍♀️🙇‍♀️thank you🙇‍♀️thank pay you back in words

[tanvigarnal]

What if you are not given the name of period but the numerical values only !!

[ishatjahan]

Can anyone tell me please please ?? Which one has the more ionization energy Al3+ or Ar??plz tell me
