chemistry -solid properties

Intermolecular Forces

Types of Solids* Intermolecular Force(s) Between Particles

1.  Metallic Crystals (Metals)
Examples:  Na, Cu, Fe, Mn
Metallic bonding:  Valence electrons form mobile
sea of electrons which comprise the metallic

2.  Ionic Crystals (Ionic Solids)
Examples:  NaCl, MgCl2, MgO
Ionic Bonding:  Attraction of charged ions for one
another. Lattice energy is a measure of ionic bond

3.  Covalent Crystals (Network
Examples (small class!):
C(diamond), SiC(s), SiO2 (quartz)
Network  covalent bonding. Network solids are
extremely hard compounds with very high melting
and boiling points due to their endless 3-
dimensional network of covalent bonds.

4.  Molecular Crystals
Examples: One or more of the following:
(a) Need H bonded to O, N or F:
H2O, HF, NH3.
(a)  Hydrogen bonding:  Hydrogen bonds are
weaker than covalent bonds, but stronger than (b)
or (c) below.
(b)  C6H6 (benzene), polyethylene,
I2, F2, and all the compounds from
(a) above.
(b)  Dispersion forces (induced dipole – induced
dipole or  London dispersion forces):  universal
force of attraction between instantaneous dipoles.
These forces are weak for small, low-molecular
weight molecules, but large for heavy, long, and/
or highly polarizable molecules.  They usually
dominate over (c) below.
(c)  CHF3, CH3COCH3 (acetone)
and H2O, HF, NH3.
(c)  Dipole-dipole forces:  these forces act
between polar molecules.  They are much weaker
than hydrogen bonding.
Note:  Van der Waals Forces is a category which includes both categories (b) and (c)

5. Atomic Crystals
Examples:  He, Ne, Ar, Kr, Xe
Dispersion forces:  See Section 4(b) above.
*Note:  Many of the compounds given as examples are not solids at room temperature.  
But if you cool them down to a low enough temperature, eventually they will become

homework time. :D

Assalamualaikum :)

arinie adlh ari homework.nyk y perlu disettlekn.smalam byk sgt,kne hbiskan mase ai nie dgn STUDY.insyaAllah.

aiseyman,mtak smpat nk wt rvision.da nak pra-UPS. uhuhuhuuhhuhu. hope i'm getting ready for all science sbjct well :)

retro permulaan

Assalamualaikum n hye pepels :)

Mood msih new,mimi decided to create new one blog.more simpler than before.just for perkongsian pngalaman n ilmu.insyaAllah.I'm not good writter but i'm writting from deep of heart :D
mimi xpndai sgt,plus minus BM and English. sori. :)

"selamat tahun baru" *sigh*

just like before,every step that i'm gonna in my life.hope it'll be the super duper GREAT,which i'll never being dissapoint soon.Amin.
y len2 simpan dlm,mlu nk ckp :)

2011 being memoir :D
welcome 2012 

Sometimes Allah tests us so that we can see the rainbow after a stormy rain. If we can’t see the rainbow in this world, then inshAllah we can in the Hereafter. Just be strong in your heart and mind! Furnish it with faith, love, trust, and sincerity for the sake of Allah. Make your imagination embroidered with His love and light. InshAllah tranquility and contentment will penetrate into our soul. That is when our imagination triumphs over intelligence.
