In this video Paul Andersen explains why atoms in the periodic table show trends in ionization energy, atomic radii, electronegativity and charge. All of these trends are explained through Coulomb's Law. A brief description of Dmitri...

In this video Paul Andersen explains how we can use Coulomb's law to predict the structure of atoms. These predictions can be verified through the use of Photoelectron Spectroscopy (PES). Electron's are help around the nucleus because...

In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law...

Discover the truth about lattice energy and why size really matters in ionic bonds. In this video, you'll learn what lattice energy is, why it's crucial in chemistry, and the factors that influence its strength. Understand how the size...

The ionisation energy decreases progressively as we move down the group. However, in the case of lead (Pb), the ionisation energy is higher than that of tin (Sn) due to inadequate shielding of the inner f-orbitals. This results in a...

The Born-Haber cycle calculates lattice energy using steps like ionization, electron affinity, and sublimation, showing the energetics of ionic compound formation

Cations, formed by electron loss, influence ionic bond strength. Smaller cations with higher charges create stronger ionic interactions

Ionization energy is the amount of energy it takes to remove an electron. The stronger the nucleus can hold on to the electron, the more energy that will be needed to remove the electron. The trend for ionization energy is that it...

This video explains how the different particles in an atom have charges, how the different particles affect the overall charges of an atom, and how atomic models are created.

Learn the basics about shielding as a part of the atomic structure, within the overall properties of matter topic.

We've already learned about different types of chemical bonds, including covalent bonds. But now that we know about enthalpy, and orbitals, and some other concepts, let's revisit the covalent bond and dig a little deeper.

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...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

It describes the properties of boron family compounds It discusses about atomic radii and ionic radii It explains the trends of ionisation enthalpy and electronegativity.

Learn the basics about the periodic table, and how the elements are organised within it in this video. The periodic table consists of 7 rows called Periods, going across, and 18 columns, called Groups going down. The elements in the...

The relationship between energy levels and strength of chemical bonds are discussed and demonstrated in this video. Students will learn that a chemical bond forms when electrons have lower energy and that less stable atoms tend to form...

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...
