Interesting facts about metals

Metals have been used by people since ancient times. All the time the process of obtaining them was improved, useful alloys of various metals appeared. Let’s look at interesting facts about metals.

Supersaturated Solution

A solution that contains a higher than saturation concentration of solute, slight disturbance or seeding causes crystallization of excess solute.

Fat

Solid triester of glycerol and (mostly) saturated fatty acids.

Beta Particle

Electron emitted from the nucleus when a neuton decays to a proton and an electron.

Actual Yield

Amount of a specified pure product actually obtained from a given reaction. Compare with Theoretical Yield.

Homonuclear

Consisting of only one element.

Heat of Vaporization

The amount of heat required to vaporize one gram of a liquid at its boiling point with no change in temperature. Usually expressed in J/g. The molar heat of vaporization is the amount of heat required to vaporize one mole of liquid at its boiling point with no change in temperature and usually expressed ion kJ/mol.

Paramagnetism

Attraction toward a magnetic field, stronger than diamagnetism, but still weak compared to ferromagnetism.

Electromagnetic Radiation

Energy that is propagated by means of electric and magnetic fields that oscillate in directions perpendicular to the direction of travel of the energy.

Ioniztion

The breaking up of a compound into separate ions.
