Vanadium at 20c is Bcc and has an atomic radius of 0.143 nm calculate a value of its lattice constant a in nanometers?
For all BCC lattice structures, the Lattice constant (a) can be found by : a = (4r) / sqrt(3)
What is ionic compounds that absorb water into their solid structure form?
Ionic compounds form giant ionic structures. Such structures are also known as giant lattice structure or crystal lattice.
What is a giant covalent lattice?
Giant covalent, lattice structures contain a lot of non-metal atoms, each joined to adjacent atoms by covalent bonds. The atoms are usually arranged into giant regular lattices. The structure requires an element with very strong bonds between the atoms to create various materials. A couple of examples are (carbon) Diamond and Buckminster Fullerine. Graphite is also one but has weak bonds as well. Silica and molybdenum can also make covalent lattice structures.
Why FCC metals are more ductile than Bcc metals?
FCC has a higher packing efficiency and the slip planes are more closely packed than BCC. Infact BCC has more slip systems than FCC. But they are not as closely packed as FCC. For plastic deformation, we need atleast 5 independent slip systems. Both FCC and BCC have those. But the previously mentioned factor makes FCC more ductile than BCC.
Why do ionic compounds form crystal lattice structures when solid?
Ionic compounds form crystal lattice structures when solid because of the strong electrostatic attraction between positively and negatively charged ions. The regular arrangement of ions in the crystal lattice maximizes the attractive forces and minimizes the repulsive forces, resulting in a stable and efficient structure.

What materials have CPH lattice structures?
zinc, cadmium, magnesium and Beryllium all have CPH structures.
What is lattice igcse?
Lattice basically refers to the shape of the given crystals based on their structures.
Is oxygen a crystal lattice?
Solid oxygen has crystalline structures.

Explain why Bcc fcc and cph lattice packing and features of grain structure affect the ductillity and brittleness of parent metallic materials?
What is FCC FCC means Face Centered Cubic Ductility is the mechanical property of a material.It is the material's ability to deform under the tensile stress without fracture.So it is depends on the atoms how they arranged in a lattice and its grain size. The ability to absorb the energy of the impact and fracture resistance depends on the arrangement of the atoms in a lattice and features of grain structure.

Does bcc is aware of bcc recipients?
No.
What is built using a framework or lattice?
A framework or lattice is the structure of crystalline materials. For example, a diamond is a lattice covalent bonded and highly organized carbon atoms lending to its super strength. Similarly salt has lattice pattern, but in this case it is from ionic attraction. Nevertheless the lattice in salt gives it the strength to have an intensely high melting point.
What materials were used in traditional SA structures?
Materials for traditional structures are usually local materials. In some parts of the world the materials may be Ice, Goat Hide, Tree Branches.
Although metals and salts have similar lattice structures metals make good materials for electrical wiring Why aren't salts used instead?
Atomic lattices (like graphite) and more specially metal atomic latice behavevery differently to electrons (current) compared with positive metal ions in their latice together with negative anions (called ionic lattice).
