Can Batteries Power Everything? This video is about the physical and chemical limitations to electrolytic batteries, and how we might surpass the energy density and specific energy of lithium-ion...

In this video Paul Andersen explains how ionic solids form when cations and anions are attracted. When atoms lose or gain electrons they form ions. The strength of the attraction between ions is based on the amount of charge and the...

They explode when you touch them. Even a millionth of a gram can kill you. They can even disable you with their horrifying smell. SciShow introduces you to give of the most dangerous chemicals in the world.

Wouldn’t it be wonderful if we could breathe underwater? But is it even possible?

All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions. As electrons...

Teflon was in the spacesuits the Apollo crew wore for the moon landing, in pipes and valves used in the Manhattan project, and it may be in your kitchen, as the nonstick coating on frying pans and cookie sheets. So what is this slippery...

If our teeth are made mostly of calcium, why do we use fluoride to keep them healthy? Quick Questions explains why, and how we finally figured it out.

Is there a way to detect diseases like cancer and Alzheimer's before they advance too far? Doctors are using injected radioactive drugs that circulate through the body and act as a beacon for PET scanners. These diagnostic tools can...

Boron trifluoride (BF₃) is an exception to the octet rule, where boron has only six valence electrons, leading to unique reactivity and electron-deficient behavior

Covalent bonds form when atoms share electrons to complete their valence shells, creating strong and directional interactions.

The reactivity of an element is a function of how easily an element loses or gains electrons. To determine an element's reactivity, we can learn a lot from the periodic table, and its particular trends. The first element in the halogen...

A class of compounds based on simple hydrocarbons like ethane, methane and propane, in which hydrogen atoms are replaced by chlorine and fluorine.

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

This video provides an overview of the element fluorine, its properties, and its uses. Despite its reactivity, fluorine is used in dental care and pharmaceuticals due to its beneficial effects on teeth and its stable carbon-fluorine...

The video discusses the history of the periodic table and how it was developed by various scientists over many years. It explains how atomic weights were initially used to organize the elements before the discovery of atomic number. It...

Let's take a look back at the elements silicon, fluorine, lithium, boron, and chromium.

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!

It's time to check out Group 17 on the periodic table, the halogens. This includes fluorine, chlorine, bromine, iodine, astatine, and tennessine. What can we say about their properties, reactivities, and applications? Let's find out!
