What is the importance of valence electrons? What are the basic properties of an ion channel? Describe the nuclear fuel cycle. What is the difference between conglomerate and breccia? Explain REDOX Rxns. What is the difference between a micelle and a chylomicron?
Explain what is meant by the 'Valence Bond Theory' and provide examples. How is the structure around a given atom related to repulsion between valence electron pairs on the atom? Describe the bonding in O_3, using molecular orbital theory. Comp...
Ionization enthalpy can be defined as the minimum amount of energy required to remove an electron from the valence shell of an isolated gaseous atom in its ground state resulting in the formation of a positive ion. It is basically the quantitative meas...
1. What is the electron configuration for chlorine? One common ion of chlorine is Cl ^1- . How many valence electrons does this ion have? 2. Explain the atomic packing (both in words and with a pictur Why is it that t...
What is the trend in the atomic size in a group, does it increase or decrease? View Solution The atomic radius increases as we move down a group because View Solution Describe the trend of atomic size along a period and a group in the periodic table. ...
Zener Breakdown is a controlled way of creating breakdown in p-n junction diodes. The p-n junction has to be heavily doped so that the electrons in the valence bond of p-type region can jump easily to the conduction band of n-type region. This temporary breakd...
the α-amylases, compared with the solution reaction, comes from. Actually, a survey of the literature regarding computational modeling of glucosidases indicates that the question of what causes their high catalytic rates basically remains unanswered. That is, computational studies in the field have ...
So, there are two columns on the periodic table for each orbital - although helium is put in the far right instead of in the second row with the other elements whose highest electron is the second one in an s orbital, because putting it on the far right shows that helium is stable ...
(a)Hydrogen is placed in the first period and first group (Group IA) in the modern periodic table. Since it has only 1 electron, it has 1 electron in its valence shell. (b) Hydrogen is placed in the same group as Li, Na, K, Rb, Cs and Fr (alkali met
Explain valence shell electron pair repulsion theory (VSEPR). What is the main assumption of the VSEPR theory? Explain in detail. Using the VSEPR theory, what is the molecular geometry (shape) of the central atom in SeCl2? a. tetrahedral b. square planar c. trigonal ...
