So I am assuming that by "the following," you mean in general terms.
The shortest wavelength of the spectrum is the Gamma Ray waves, they are 400nm and are the most deadly, because of how often and frequent they are able to vibrate. Shorter the wavelength the more active.
So the list from "shortest," to "longest," is,
Gamma Ray, X-Ray, Ultraviolet, Visible, Infrared, Microwave, and Radio wavelengths.
In the spectrum, Radio has the longest and furthest traveling waves. This means that they are not harmful and that they can travel extreme distances.
Hope this helps!
Answer:
Crystal structure
Explanation:
The repeated pattern of similar particles in a material is called crystal. Crystal structure is the largest constituent unit of a solid matter.
The fundamental identity of a crystal structure is a unit cell that is formed by the arrangement of atoms or ions in a particular manner. A crystal is defined as a regular, long-ranged repeated arrangement of unit cells.
Crystal have a sharp melting and boiling point and they give a sharp edge on being cut with a knife.
Answer: the answer should be 6,720 decameters.
Answer:
1) D
2) A
Explanation:
1) Each group has the same number of valence electrons, which are the outer electrons.
2) Ionic bonds are between a metal and non - metal, the metal being sodium and the non - metal being chlorine.
