Definition: A pale yellow, poisonous gas that is very reactive and belongs to the group of elements known as halogens. It is used in many important industrial processes and is the most electronegative element.

Example: Fluorine is used in the production of certain types of plastics and chemicals.

Definition: A type of mineral that is made of calcium fluoride and can be found in various colors. It often glows under ultraviolet light and is used in making glass and steel.

Example: The geologist collected samples of fluorite to study its properties.

Definition: A type of dye that glows under certain light, used to color biological samples for study.

Example: The scientist used a fluorochrome to highlight the cells in the tissue sample.

Definition: A device used to detect and measure the light emitted by a substance when it is exposed to radiation, particularly in the context of fluorescence.

Example: The scientist used a fluorometer to analyze the samples for their fluorescent properties.

Definition: Relating to a method of measuring the intensity of fluorescent light emitted by a substance when it is exposed to light.

Example: The fluorometric analysis revealed the presence of trace elements in the sample.

Definition: A method used in science to measure and analyze the light emitted by substances when they are exposed to light, helping to identify and quantify small amounts of those substances.

Example: The scientist used fluorometry to analyze the samples for contaminants.

Definition: A mineral composed of calcium fluoride, often used in the production of aluminum and in the manufacture of certain types of glass.

Example: Fluorspar is an important source of fluorine for various industrial applications.

Definition: Having a surface that is decorated with long, narrow grooves or channels.

Example: The fluted columns added an elegant touch to the building's design.

Definition: To make a sound like a flute or to play a flute, often used in a musical context.

Example: She fluted a beautiful melody on her instrument during the concert.

Definition: A person who plays the flute, often referred to as a flutist or flautist.

Example: The fluter performed beautifully at the concert last night.

Definition: A device that uses soft iron cores and coils of wire to detect and measure magnetic fields, often indicating their direction and strength.

Example: The scientist used a fluxgate to measure the Earth's magnetic field during the experiment.
