Across the southeastern United States, bald eagles have been dying unexplainedly for the past 25 years. In March of 2021, researchers announced that they had found the killer, and they hope we can use this knowledge to better protect...

The chemistry behind film photography is pretty fascinating. How do film cameras help us turn light into a physical image?

Hank squares off against the host of SciShow Kids, Jessi Knudsen Castaneda, to match wits about chemistry, evolution, and how babies are weird!

We’ve talked about benzene a bit already in this series, but did you know that benzene rings are present in all kinds of familiar substances? The styrofoam packaging that comes with new appliances, some pharmaceuticals, pesticides, and...

Anions, formed by electron gain, contribute to ionic bond formation. Larger anions with higher charges enhance the bond's electrostatic attraction

Halogens are hazardous to human life, yet they can also be very useful. How do they react when they meet other elements? Chemistry - Periodic Table - Learning Points. The halogens are the elements in Group 7 of the periodic table. The...

Learn all about single replacement chemical reactions. We'll break down the process and give examples to help you understand this important topic. Perfect for studying for your chemistry test or just brushing up on your knowledge.

Writing electron configurations can be a long and daunting task, until you learn the shortcut! Often times called the noble gas configuration, the shorthand notation will have you writing electron configurations very quickly! In this...

This video covers:

- The idea that the carbon-carbon double bond can break, which allows the carbons to bond to new a
toms
- How alkenes react with hydrogen to fo
rm alkanes
- How alkenes react with water to
form...

Learn all about the properties and trends of the group 7 (halogens) and group 0 (noble gases) elements. Including why halogens become less reactive as you go down the group, and why noble gases are so unreactive. Suitable for: Combined...

Main groups in the modern periodic table | Summary

Large reductions in the amount of perennial ice in the Arctic due to climate change may be driving mercury pollution, according to a new report from NASA. When sunlight reacts with salt in the new ice at cold temperatures, bromine is...

Looking at how E2 reactions occur on cyclic substrates.

In this video, we will determine the Lewis structure for a given compound.<br/>

Looking at carbonic acid and its derivatives.

Introducing the E1 reaction.

This reaction comes to us thanks to a German husband and wife chemist team! Isn't that romantic? And it allows us to convert a carboxylic acid into an alkyl halide, which is very neat. Oh, and there's radical chemistry! Of course you...

A colder than usual winter in the southern hemisphere fed a deep and larger than average hole that persisted for a longer period than usual.

Halohydrin Formation: Theory, Mechanism, Examples

We learned about how pairs of protons can have specific relationships. They can be homotopic, enantiotopic, diastereotopic, or heterotopic. Let's apply this to some examples!

An overview of several addition reactions.

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...
