From SAED pattern from TEM how you determined which element is present?
you have to measure the distance and angles between the main point and the surrounding pattern from the diffraction you create. Each crystal has its own structure (BCC, FCC, HCP, etc...) and each element in the crystal structure determines the lattice spacing....
What is structure of zinc crystal?
It is a box shape. Here is some more info on the subject matter pertaining to your specific circumstances:Space group: P63/mmc (Space group number: 194)Structure: hcp (hexagonal close-packed)Cell parameters: a: 266.49 pm

What are the three differences packing arrangements found in metallic crystals?
Most metals and alloys crystallize in one of three very common structures: body-centered cubic (bcc), Li is an example of bcc , hexagonal close packed (hcp) Au is an example of hcp, or cubic close packed (ccp, also called face centered cubic, fcc) Ag is an example of fcg. The yield strength of a "perfect" single crystal of pure Al is ca. 10^6 psi.
What are facts about beryllium?
Beryllium is an alkaline-earth metal, atomic number 4, atomic mass 9,01282(3); very toxic, it is the cause of berylliosis.Applications:- alloying metal for copper alloys (alloys for welding electrodes, components in electrotechnics, springs for watches - from glycodur)- rockets, missiles, aviation- brazing material for zirconium and zirconium alloys- reflector in nuclear reactors (as metal or oxide)- windows for X-ray tubes or X-ray detectors- component of neutron sources (Ra-Be, Pu-Be, Am-Be, Po-Be, etc.)- components for large particles accelerators- mirrors for astronomy, military armored vehicles, etc.- special components for electronics- beryllium oxide: ceramic material for burning boats, tubes of reaction, crucibles, tubes for thermocouples, thermal isolator in electronics, etc.- BeF2 was used in the experimental reactor MSRE- beryllium nitride (Be3N2) is a refractory ceramics and the the source material to prepare the isotope 14C- and other applications1. The colour of Beryllium is a steel grey2. The structure of Beryllium is HCP (hexagonal close packed)3. Beryllium and its salts are both toxic and carcinogenic4. It has high thermal conductivity and is nonmagnetic

Number of atoms in hcp unit cell?
"There are 6 atoms in the hcp unit cell. The hex shape has six atoms at the points that are direct translations of each other making 1 atom for the top hex and one atom for the bottom hex. That's 2. The atom in the center of the top and center of the bottom are translations giving 1 more. That's 3. Then there are 3 atoms in the middle region of each cell bringing the total to 6." The answer should depend on how you choose your unit cell. In the primitive hexagonal cell we have 1 atom at each of the corners of the cell (each is "worth" 1/8) and 1 atom within the cell giving us 2 atoms/unit cell. (Note: the 'primitive hexagonal cell' above actually refers to the parallelpiped structure that the hexagonal unit cell consists of: the hexagonal 'unit' -it cannot technically be referred to as a unit cell, because unit cells are the most reduced form of the crystal structure- can be divided into 3 parallelepipeds.)
What is the structures of AB2 type ionic crystal?
Fluorite (CaF2 as an example) and rutile (TiO2 as an example) are the big two. Also existing are the CdI2 and CdCl2 structures (CCP and HCP respectively).
Volume of a HCP unit cell?
The volume of HCP is 8*pi*r^3 or 25.13*r^3

How would you describe hereditary coproporphyria?
HCP is similar to AIP, but the symptoms are typically milder. People with HCP may have some skin sensitivity to sunlight, however, extensive damage to the skin is rarely seen.
