By using positive ray analysis he was able to correlate different ionisation potentials with the production of ions of different ratio of mass to charge. I have now used the same apparatus to ...

After 1950, when the previous edition was published, advancing technology made possible a great deal of experimental work on the properties of negative ions in gases. Photodetachment techniques became ...

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 ...

The atom is neutral as it has two positive protons and two negative electrons. A helium atom that has lost or gained an electron is an ion.

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 ...

Totalling the charge on the left hand side gives an overall charge of 12+ (the total of the charges on the negative dichromate ion and positive hydrogen ions), while the right hand side is 6 ...

When solar wind strikes the Moon, it releases secondary particles, including positive, negative, and neutral ions. Detecting negative ions, which are short-lived and cannot reach orbit ...
