How do we represent an atom, with all of its protons, neutrons, and electrons? With nuclide symbols, of course! These show the type of element, as well as the atomic number, mass number, and electrical charge of an atom. That's all you...

In this video, we explore the groundbreaking discoveries of JJ Thompson and his plum pudding model of the atom. Thompson's experiments with electric currents and magnetic charges led him to hypothesize the existence of negatively charged...

What's the difference between a physical change and a chemical change? What are elements, compounds, pure substances, and mixtures? So many definitions to learn! Don't worry, Professor Dave will take you through the details.

I this video you will see how we can use the periodic table to tell us more about the differences between elements, including the different numbers of protons, neutrons and electrons they possess.

Doodle Science teaches you high school physics in a less boring way in almost no time!

Upon viewing the Forming Bonds video series, students will be able to do the following: Understand that matter is made up of tiny particles called atoms. Explain that atoms consist of many different types of subatomic particles including...

Upon viewing the Exploring the Building Blocks of Matter video series, students will be able to do the following: Understand that the quest to better understand the building blocks of matter has transpired over the past several thousand...

In this video, the teacher explains the concept of isotopes - atoms of the same element that have different numbers of neutrons.<b<br/>r/>

Atoms part 10/13

In this video, the concept of the nucleus in an atom is explained, highlighting its significance as the dense core containing over 99% of the atom's mass. Additionally, the importance of the atomic number in distinguishing different...

In this video, the concept of mass number is explained, using the example of sulfur. The video also introduces the idea of isotopes, using carbon as an example, and explains how the atomic mass is calculated as a weighted average of the...

Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary...

This video explains how electrons are arranged in atoms and how their arrangement affects the bonding between atoms. The video also highlights the importance of valence electrons, which are the electrons in the outermost energy level, in...

Atoms don't just appear and disappear into thin air, you silly goose. What are you, a magician? When we have a chemical equation we will have to balance it. Here's how to do it!

This video describes the basic role that atoms play in creating electrical charges, as well as the nature and creation of static electricity. Various methods of charging are discussed, emphasizing the role that insulators and conductors...

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...
