Coulomb's Law Explained!
Coulomb’s Law is one of the most important laws when it comes to atomic structure and being able to understand and explain atomic properties. It helps to relate the force between two charged particles and can be represented by the...

Electronegativity Periodic Trend - Using the Periodic Table to help determine electronegativity!
Electronegativity is the tendency of an atom to gain an electron. The way I think about it is like tug of war. The stronger an atom can pull in an electron, the higher it’s electronegativity will be. The trend for electronegativity is...

Practice Problem: Atomic Radii and Ionic Radii
We've learned all about the periodic trends, including atomic radius, so let's put our knowledge to the test! Here we will have to put some atoms in order of increasing atomic radius, and then do the same thing for some ions and their...

IIT/JEE Chemistry Practice #15: Electronegativity/Ionic Radii
Practice REAL problems from actual past IIT/JEE exams with Professor Dave!
Professor Dave Explains
Practice Problem: Ionization Energy
When we learned about periodic trends, we learned about ionization energy. Just how much energy is required to remove an electron from an atom? What about a second electron, or a third? Let's compare a few different ionizations and see...

The Periodic Table: Atomic Radius, Ionization Energy, and Electronegativity
Why is the periodic table arranged the way it is? There are specific reasons, you know. Because of the way we organize the elements, there are special patterns that emerge. And you know how Professor Dave feels about patterns. He likes...
