It involves the interaction between all pairs of atoms excluding the bonded atom as it is already involved in bonded term. For weak dipole attraction and repulsion depending upon distance between atoms is accounted by the Lennard-jones potential which is given by:- 2) VMD :- It is a program for molecular visualization‚ modelling and analysis of biological systems like proteins‚ nucleic acid‚ and lipid bilayer assemblies. VMD also gives option to work with volumetric data‚ sequence data

to eat. It does not require light‚ and is interestingly called the "dark cycle" 1. The first step of this cycle consists of A carbon atom from carbon dioxide molecule will enter the cycle and joins with a five carbon molecule that is present. 2. The six carbon molecule that results from that compound breaks up into two molecules‚ each with three carbon atoms. 3. As the reactions in the cycle continue‚ ATP is dephosphorylated (loses a phosphate) to ADP. The energy that is released is used

different number of neutrons‚ therefore a different mass. 4. Positively charged ions are formed when atom _loses_ (lose‚ gain) electrons. 5. Calculate the atomic mass of the following sample of Silicon. 92.21 % 28Si‚ 4.70% 29Si‚ and 3.09% 30Si. Answer to 2 decimal places‚ remember units. 0.9221 x 28 = 25.8188 amu 0.0470 x 29 = 1.363 amu 0.0309 x 30 = 0.927 amu 28.1088 amu = 28.11 amu 6.

His theory stated that atoms were invisible and indestructible. Since Democritus did not really have that much technological support at the time‚ he could not elaborate on his suggestion. That’s where John Dalton came in…..2000 years later. Dalton used experimental methods to

Trends in the Periodic Table * Generally‚ the atomic radius decreases across a period from left to right and increases down a given group. The atoms with the largest atomic radii are located in Group I and at the bottom of groups. Moving from left to right across a period‚ electrons are added one at a time to the outer energy shell. Electrons within a shell cannot shield each other from the attraction to protons. Since the number of protons is also increasing‚ the effective nuclear charge increases

strongest chemical bonds. An ionic bond forms when two atoms differ so much in electronegativity that one or more electrons are actually transferred from one atom to the other. Ionic bonds generally occur between a metal and a nonmetal. Due to the existence of ionic bonds‚ elements that normally would not combine because sharing electrons is either not possible or not practical may be combined to form chemical compounds. A covalent bond forms when two atoms share a pair of electrons. The sharing of one pair
