Stereochemical structures refer to the three-dimensional arrangement of atoms in a molecule. They include configurations such as cis-trans isomerism, optical isomerism, and geometric isomerism, which affect the physical and chemical properties of the molecule. Knowledge of stereochemical structures is important in understanding the reactivity and behavior of organic compounds.

The three basic categories of astronomical observation are optical, radio, and space-based. Optical observations involve using telescopes to detect visible light; radio observations involve detecting radio waves from celestial objects; space-based observations are done using telescopes and satellites positioned outside Earth's atmosphere to observe different wavelengths of light.
Astronomers use radio telescopes, infrared telescopes, and space-based telescopes to map the shape of the Milky Way. They measure the positions and motions of stars, gas, and dust to create a three-dimensional map of our galaxy.
Deuterium, also known as heavy hydrogen, exhibits three separate properties: Physical properties, quantum properties and nuclear properties (the deuteron).
1) light-gethering power, 2) resolving power, and 3) magnifying power
The three major types are the optical, the infrared, and the radio telescopes. There are other specialized instruments for observing gamma rays, or x-rays, or for doing processes such as interferometry. Among the optical telescopes are the refracting (lens), reflecting (mirror) and compound telescopes (computer-assisted combinations of several smaller telescopes to simulate a much larger one).

Three size-dependent physical properties are surface area, melting point, and optical properties (such as color or transparency). These properties can change as the size of a material decreases, leading to different behaviors and characteristics at the nanoscale.
They are extremely important because they give us a view of the universe that is betterthan the telescopes on the ground.
The two types are refractor and reflector. In a refracting telescope, the light comes in THROUGH a magnifying LENS where it is REFRACTED (bent) to focus the light into an objective lens. In a reflecting telescope, the light BOUNCES OFF a curved magnifying MIRROR , and then reflected again on a secondary mirror to direct the light into an objective lens. Among the advantages of a reflecting telescope are that in a refracting lens, the thickness of the lens can absorb some of the light, while a mirror reflects all of the light. Additionally, a reflecting telescope can "fold" the telescope into a much more compact instrument, which is essential with especially large devices. A large refracting telescope would be enormously heavy and cumbersome.

The three properties of color are the spectrum, the chromaticity, and the primary colors
the three basic properties in addition are associative, indentity,and commutative.
