Miller indices form a notation system in crystallography for planes in crystal (Bravais) lattices. In particular, a family of lattice planes is determined by three integers.
a) Draw the following planes of Miller Indices in the given cubic lattice.
i. (0 1 1)
ii.(1 3 2)
iii.(1 0 2)
iv.(0 2 1)
v.(2 0 2)
The highest energy electrons in an atom Q have the principal quantum number n = 4 and the angular quantum number l = 0. What is the maximum number of electrons present in atom Q?
An atom X contains eight electrons in s orbitals, twelve electron in p orbitals, and eight electrons in d orbitals. Write the electronic configuration of X and determine what is atom X?
A cubic solid is made of two elements P and Q. All P cations are located at the corners of the unit cell and six Q anions on the center of all the cubic faces.
i. Draw a structure of the cubic mentioned above.
ii. What is the coordination number of Q?
iii. What is the formula of the compound? Show your work.
Solid materials can be classified into three different categories named crystalline, polycrystalline and amorphous. Advance studies in material chemistry lead to development of technology and innovation.
(a) Define the factors that should be taken into consideration when innovating new materials.
(b) What makes crystal is different from amorphous material? Give one example for each type of materials.
a solid mass of 25 g is mixed with 60 g of a solution. A chemical reaction takes place and a gas produced. the final mass of the mixture is 75 g. what is the mass of the gas released
