1. On the basis of Thomson’s model of an atom, explain how the atom is neutral as a whole. Ans:As per Thomson’s model of an atom, the number of electrons and the number of protons are equal in an atom. Electrons are positively charged and protons are negatively charged, hence the...
Atoms are defined as“the basic building blocks of matter”. Atom is the basic of all matter. They are very small and consist of even tinier particles. Neutrons, Protons, and Electrons are the basic particles making up the atom. They join together with other atoms and create matter. It ta...
Explain why the the structure of a molecule/compound is important. Compound: The compound is the homogeneous mixture of one or more same or different substituents in a fixed ratio. For example, hydrochloric acid has the molecular formula of HCl which is obtained when hydrogen and chlorine...
Each neutral H atom passing through the shock front emits on average about 0.1 H伪 photon before it is ionized. Since this radiation arises very close to the shock front, rather than in an extended post-shock cooling zone (2), it can be used to study the physics of the shock front ...
Topic 1: The changing models of atomic structureThis topic will highlight the changing models of atomic structure and how sequence of experiments, observations, analysis and conclusions led to the modern day model of atom. The content of the article will be restricted to AS/A-level students....
where, V: Total number of valence electrons present in the free atom N: Total number of non-bonded electrons or lone pairs B: Total number of bonded or shared electrons The molecules in which the atoms possessing the smallest formal charge are considered to have the lowest energy and more...
The higher affinity of cPknF for FHA-2 is important for further conformational changes. • Rv1747 activation model reveals a concatenated activity essential for the system. Abstract Mycobacterium tuberculosis (Mtb) has 11 Serine-Threonine Protein Kinases (STPK) that control numerous physiological proc...
The general idea is that, number of bands=number of lines. For instance, AlAs primitive cell (one of each atom per cell) has 13 bands; that is outer most shells have 13 distinct energy values. (Al: one 3s + three 3p, As: five 3d + one 4s + three 4p) But when I calculate Band...
Describe the structure of an atom and the role of electrons in forming bonds and interactions between atoms that form molecules. What are some of the ways that the structure of molecules can be shown? What is the molecular geometry of a molecule with 4 outer atoms and 1 lone pair on the...
Fig. 2: All-atom model of theE. coliCSU. aComponent models used for initial CSU assembly, including the protein interaction region of the Tsr receptor trimer-of-dimers (TOD) and homology models of the CheA.P3-P4 and CheA.P5-CheW interface 1 dimers. Receptors are colored in red, CheA in...
