Over 200 years ago, scientists were looking at sunlight through a prism when they noticed that part of the rainbow was missing. There were dark lines where there should have been colors. Since then, scientists have unlocked the secrets...

Today I’m going to explain why you’re not falling through your chair right now using one simple fact, and one object. The fact is that all electrons are the same as each other, and the object is a structurally critical item of my...

It's really difficult for life to create blue pigments, but the color can appear in a handful of compounds that create just the right conditions to reflect blue photons.

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...

Why do certain elements have similar properties? Because of the way electrons are arranged around the nucleus of atoms. But why are electrons arranged specifically in certain orbitals and shells? The structure of...

Line spectra are unique patterns of light emitted or absorbed by atoms, resembling discrete lines. These patterns serve as the "fingerprints" of different elements, providing critical insights into atomic structure and composition....

In 1913, Niels Bohr proposed an atomic model that dramatically altered our comprehension of atomic structure by establishing a novel framework for describing the arrangement and behaviour of electrons within an atom....

Explore the fascinating journey to uncover the universe's missing baryons—ordinary matter that had eluded scientists for decades. From the origins of baryonic matter after the Big Bang to groundbreaking discoveries using fast radio...

Emitting Radiation | Radioactivity | Physics | FuseSchool What do you think of when you hear the phrase “emitting radiation”? Do you think it’s a good thing or a bad thing? What if I told you it was vital for life on Earth? In this video...

This nugget explains the features and mathematical expressions of Bohr's model and its advantages over Rutherford's model.

It's time to start our survey of the periodic table, and we are going to start with just one element, hydrogen. This is the most abundant element in the universe by a wide margin. What does it do? What are its properties? What are its...

Imagine if engineers could build a computer to be millions of times faster than anything that exists today, yet so small it's microscopic. John Preskill, a theoretical physicist at the California Institute of Technology, explains the...

It explains bonding, properties & limitations of Valence bond theory & crystal field theory of coordination compounds.

How a superconductor works. Everything from the physics and some of the history as well. Superconductors were discovered in 1911 by Heike Kamerlingh Onnes. It was discovered because it was made possible to liquefy helium which produced...
