Early atomic physics - the development of the first ideas. The first ideas started with Democritus: atom is unsplittable. Then John Dalton Law of constant proportions. Avogadro: Molecular theory of gas laws. Prout's hydrogen weight...

The explanation covers the electron configurations, quantum mechanics, and relativistic effects that determine these properties. This video is perfect for anyone curious about the science behind element properties....

We didn’t always know exactly what the atom looked like. Even today we’re not entirely sure – but we have a far better idea than ever before! In this video, we’re going to...

In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but...

In this video Paul Andersen explains how elements and molecules are made of atoms. In a pure sample of a pure substance the average mass remains the same. If more than one atom is found in a molecule the ration of average masses...

Adamantium, bolognium, dilithium. Element Zero, Kryptonite. Mythril, Netherite, Orichalcum, Unobtanium. We love the idea of fictional elements with miraculous properties that science has yet to discover. But is it really possible that...

For thousands of years, water was thought to be an element. That is, until some of the greatest chemists in the world managed to crack it open.

How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud...

Przybylski’s Star has been puzzling astronomers for decades, and it might contain elements or isotopes that scientists have never seen before!

This video provides an overview of the structure and notation of atoms, including the positively charged nucleus, negatively charged electrons, protons, neutrons, and the arrangement of electrons in energy levels. It also explains how to...

Why does changing just one proton in the nucleus of an atom make a different element? How can a single proton make such a huge difference in an element’s properties?



The simple answer is: The number of...

In this video, we'll explore what atoms and ions are, and what the differences are. We'll also talk about how they're used in chemistry and physical science.

Atoms are tiny particles that are so small they are not possible to see with the naked eye, and are only barely possible to make out with the most powerful microscopes. Everything that exists in our universe is made up of atoms –...

The identity and chemical properties of any atom are determined by the number of protons in its nucleus. As atoms get bigger and heavier, the nuclei get bigger and heavier and the protons need a “nuclear glue” to help hold them together....

Then Isaac Newton in 1687 showed that planets move due to the same forces we experience here on earth. If things could be explained with mathematics, to many people this called into question the need for a...

Tetrahedron formation is a crucial aspect of the chemical bonding and molecular geometry of Group 4 elements like carbon, silicon, germanium, tin, and lead. The tetrahedral shape is formed by the arrangement of four substituents around...

Bob Lazar and area 51. Element 115. Could the fluxliner or alien gravity propulsion system work? In a 2018 Netflix documentary, Bob Lazar claims to be a physicist who worked for a very secret site called S-4, near...

When a radioactive atom goes through alpha or beta decay, the atom itself changes into a different element. For example, carbon-14 decays to nitrogen-14 when it emits beta radiation. It’s impossible to predict when an individual atom...

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.

Physical Science for Kids is the fun way to learn important facts about physical science and get ready for tests. Take a fascinating journey to the Super Science Station to learn about the elements.

We know everything is made up of atoms, but have you ever wondered how an atom is made? If you want to know how to click on the link below where we explain HOW TO BUILD AN ATOM with the help of a simulator.

It explains occurrence, electronic configuration, atomic and ionic radii, ionization enthalpy, physical and chemical properties of GROUP 16 elements.
