Time to dig into the truth on this common food and drink preservative. “Sulfites are chemical compounds that contain a sulfur ion,” explains Amy Davis, RD, LDN, registered dietitian at FRESH ...

will occupy the latice points that define the face centered cubic unit cell, with the zinc ions occupying the tetrahedral holes. Since there are four sulfide ions (FCC), we need only four zinc ions to ...

But there's another thing people often cite as a concern when it comes to wine: sulfites. But should people be concerned ...

And while batteries themselves aren’t some new technology, the lithium-ion (Li-on) kind that powers most of our devices only began gaining ground a few short decades ago. But just as the world ...

Although several types of excitable cells exist — including neurons, muscle cells, and touch receptor cells — all of them use ion channel receptors to convert chemical or mechanical messages ...

The attraction by chlorine is stronger than the attraction by sodium. An electron is transferred from sodium to chlorine. Sodium becomes a positive ion and chlorine becomes a negative ion. The ...

Here’s how it works. It's hard to describe how well the Ion works without getting too lurid for T3. Safe to say, it's effective. While some of its peripheral functions aren't quite perfect ...

In addition to being in minerals, lithium can be found in brines and ocean water because of its solubility as an ion. This means lithium saturated brines found in South America and Nevada can be ...

A dot and cross diagram for sodium chloride suggests that it is made up of pairs of sodium and chloride ions. It is not. A 3D construction model shows how the ions are arranged in a lattice structure.

Show the photo: Magnified salt (JPG). Explain that this is a magnified picture of salt crystals. Tell students that each salt crystal is made up of two different types of particles called sodium ions ...

Ion exchange resins are materials — composed of organic polymer beads or membranes — which simultaneously trap and release ions for the purpose of purifying or decontaminating liquids. Ions are ...
