Elements themselves are not crystalline or amorphous. Instead this describes the structure of certain elements and compounds in the solid state. For instance, a single element can be found in both a crystalline form as well as an amorphous form. A crystalline solid is one in which there is a regular repeating pattern in the structure, or in other words, there is long-range order. In fact, you can completely describe the entire crystal by describing the single "repeat unit." For instance, as a simple example, if I have the pattern ABCABCABCABCABC... (that repeats infinitely) I can completely describe it by just saying it is "ABC" over and over again. In a 3-dimensional crystal, this repeat unit is called the "unit cell." Some crystalline solids are diamond, table salt, and many types of minerals found in the earth. An amorphous solid is one which does not have long-range order. In other words, there is no repeat unit. To contrast the example above, it would now be: ABCBCABBCACBACBAC... where there is no way to figure out what will be the next letter. Some examples of amorphous solids are glass (in windows, for example), wax, and plastics. If a liquid cools very quickly, the molecules will not have time to arrange themselves in the most favorable pattern (which will almost always be crystalline), and so they are locked into a disordered solid. Silicon is a common solid that can be found in both amorphous and crystalline forms, depending on how it is manufactured. Crystalline silicon is much harder to grow, but it is what is used in computer chips. Amorphous silicon is much cheaper and easier to grow, and is commonly used in solar panels.

Classification of matter according to its composition?

When the content of the matter is considered, there are elements, compounds and mixtures. If the shapes are concerned, there are crystalline and amorphous matter.


What is an amorphous compound?

A compound of one or more elements that lacks crystalline structure or is unformed.


What are the differences between elements and compounds?

Elements cannot be broken down into simpler materials - compounds can. Or . . . compounds are made from elements.


What are differences between elements and compounds?

Elements are only single, whereas compounds are two or more elements bonded together, for example, Hydrogen is a single element but Hydrochlroric Acid is Hydrogen and Chlorine.


Are compounds in a mineral arranged in a repeating pattern to form crystals?

The atoms of the chemical compounds or elements that compose a mineral are arranged in repeating interlocking patterns which form the crystalline structures.


What is differences between compounds and elements?

Elements are made of one kind of atom. Compounds are made of more than one kind of atom (more than one element).


Is crystal a mixture compound or element?

A crystal can be any of these forms of matter. Crystalline compounds and elements are common, some alloys are crystalline mixtures of two or more metals, and some complex crystals such as zeolites can have varying amounts of different elements included within them.


Does a mineral have to be composed of two or more elements?

No. There are elemental minerals, like gold, silver, and copper, appearing in crystalline form. The bulk of minerals, however, are compounds of two or more elements.


How are elements and compounds similar and how do they differ?

DIFFERENCES• Compounds have two or more different types of atoms.• Elements are pure substances that have the exact same type of atom.SIMILARITIES• They are both pure substances.


Compare and contrast elements and compounds?

Elements make up compounds. Compounds cant make up elements. Compounds are bigger than elements. Elements are smaller than compounds.

Is amorphous urate normal in urine?

Amorphous urates are normal in urine. There are several types of amorphous crystals, each composed of different elements and forming in specific urine conditions. Amorphous crystals are misidentified as bacteria.


How are elements and compounds alike and different?

The only similarity elements and compounds share are that they're the building blocks of matter. Their differences are that elements are are made of only one type of periodic element. Compounds are made of at least two periodic elements bonded together. For example, salt is a compound of sodium-chloride and the helium in balloons is made up entirely of helium molecules.


How much does boron cost?

Crystalline Boron costs approximately $5,000 Amorphous Boron costs approximately $2,000 Amorphous Boron can be used for pyrotechnic flares (which makes it turn a bright green color) and it can ignite rockets.

None. Elements do not contain compounds. It is compounds which contain elements.


What do elements and compounds have in common?

Elements and compounds are both composed of atoms. Compounds are composed of two or more atoms of different elements.


Where are elements listed and why compounds are not found there?

Elements are listed in the Periodic Table of Elements. Compounds are not listed there because they are not elements they are compounds. An element is a substance made up of one type of atom, compounds are formed from combinations of different elements.
