In this video we are going to look how to name binary ionic compounds. These compounds deal with the ionic bonding of 2 different elements. Remember that an ionic compound is formed between a metal and a nonmetal or a cation and an...

A covalent compound is formed when 2 nonmetals bond together. When we have a covalent compound we have to use a specific set of naming rules. The first rules is that the first element keeps its name. The second rule is that the second...

Molecules like PF5, SF₆ defy the octet rule, with expanded valence shells or unpaired electrons, arising from the availability of d-orbitals or radical stability

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...

Access to safe drinking water is a global problem for nearly a billion people. For approximately 200 million people, many in Africa, high levels of naturally occurring fluoride in the water causes disfiguring and debilitating dental and...

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...

Polarizability (Part 2/2)

Shark teeth contain fluoride, the key ingredient in most toothpastes, according to the study, recently published in the Journal of Structural Biology. The enamel of shark teeth contain the mineral fluoroapatite, instead of...

A PRIEST in India suffers from a mystery medical condition that has made his body shrink and his bones bend. Bharat Tiwari, from Madhya Pradesh, suffers from a rare condition that has never been diagnosed by doctors, with local villagers...

We've learned that there are ionic solids that are insoluble in water, and while for the most part that's accurate, we are bending the truth a little bit. Even compounds that are totally water insoluble will still dissolve a teeny tiny...

We know that within an ionic compound, the ions are held together by ionic bonds. What is the strength of those bonds, and what is the lattice energy possessed by the entire lattice? Can we compare two compounds and say which has the...

Need some organic chemistry practice? Here's a tricky mechanism to try!

The last step before learning about the types of reactions in which transition metal complexes participate is to learn about the Hard/Soft Acid-Base Theory. To put it simply, hard means low polarizability, while soft means high...
