Deutsch: Halogene / Español: Halógeno / Português: Halogénio / Français: Halogène / Italiano: Alogeni
A halogen is a member of the chemical group of halogens. It is the only periodic table group that contains elements in all three familiar states of matter at standard temperature and pressure. All of the halogens form acids when bonded to hydrogen. Most halogens are typically produced from minerals of salts. The middle halogens, that is, chlorine, bromine and iodine, are often used as disinfectants. The halogens are also all toxic.

Deutsch: Hygrometer / Español: Higrómetro / Português: Higrômetro / Français: Hygromètre / Italiano: Igrometro

A hygrometer is an instrument used for measuring the moisture content in the atmosphere. Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, mass or a mechanical or electrical change in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can lead to a measurement of humidity. Modern electronic devices use temperature of condensation (the dew point), or changes in electrical capacitance or resistance to measure humidity differences.
