Molecular solid:
A solid which consist of atoms or molecule thought intermolecular force.
Metallic solid:
The solid which consist of metal atom held together by metallic bonds. Metallic bonding is chemical bond formed by attraction between cation of metal and the surrounding sea of electrons.
Ionic solid:
A solid which consist of anions and cations held together by ionic bond (electrical attraction of opposite charges).
Covalent network:
A solid that involves atoms held together by great network or shackles by covalent bonds.
Diamond and graphite are great example.

- 8.13 What is the coordination number of atoms in the diamond structure?arrow_forward12. Which one of the following statements is INCORRECT: (A) X-ray crystallography can give the three-dimensional arrangement of all the atoms in a molecule The ratio of the two main isotopes of Cl (chlorine) is about 3:1 (B) (C) The index of hydrogen deficiency (IDH) for C5H8O is 4. (D) Generally speaking, the longer the wavelength of the UV-Vis spectrum maximum (2max), the more conjugated the molecule is. The energy of photons used in UV-Vis spectroscopy is much higher than those used in NMR spectroscopy. (E)arrow_forwardExplain :(a) List two differences between metallic and ionic crystals.(b) Sodium chloride is hard but sodium metal is soft.arrow_forward
- Which of these statements about alloys and intermetallic compoundsis false? (a) Bronze is an example of an alloy. (b) “Alloy”is just another word for “a chemical compound of fixedcomposition that is made of two or more metals.” (c) Intermetallicsare compounds of two or more metals that have a definitecomposition and are not considered alloys. (d) If you mixtwo metals together and, at the atomic level, they separate intotwo or more different compositional phases, you have createda heterogeneous alloy. (e) Alloys can be formed even if the atomsthat comprise them are rather different in size.arrow_forwardWhat are the various phases of SiO2?arrow_forwardAn ideal quantum dot for use in TVs does not contain anycadmium due to concerns about disposal. One potentialmaterial for this purpose is InP, which adopts the zincblende (ZnS) structure (face-centered cubic). The unit celledge length is 5.869 Å. (a) If the quantum dot is shaped likea cube, how many of each type of atom are there in a cubiccrystal with an edge length of 3.00 nm? 5.00 nm? (b) Ifone of the nanoparticles in part (a) emits blue light and theother emits orange light, which color is emitted by the crystalwith the 3.00-nm edge length? With the 5.00-nm edgelength?arrow_forward
