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 ...

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.

The positive areas of the water molecules surround the negative Chloride ions. The negative areas of the water molecules surround the positive sodium ions. As the attractions from the water molecules ...

A white precipitate forms if sulfate ions are present. Explain why, in a test for sulfate ions, the sample is acidified with hydrochloric acid first. Carbonate ions also produce a white ...

Rubidium could be the next key player in oxide-ion conductors. Researchers have discovered a rare rubidium (Rb)-containing oxide-ion conductor with exceptionally high conductivity. Identified through ...

Rubies and emeralds have the colors they do because, like many substances, they absorb some colors of light. Most visible light, like sunlight, is composed of all the colors of the rainbow: red, ...

For decades, scientists have sought ways to counter our dependence on lithium-ion batteries. These traditional, rechargeable ...
