Describe the nuclear model of the atom. How does this model explain the results of alpha-particle scattering from metal foils? Classify the nuclear equations. \\ ^{249}_8 Cf + ^{15}_7 N \rightarrow ^{260}_{150} Db + 4 ^1_0 n \\ a. fission b. fusion c. natural radioactive ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
∴Sample answer:The hydrogen atom is composed of a proton nucleus and an electron. A proton is a hadron consisting of three quarks ie two up quarks, and 1 down quark. The quarks are bound together through the strong nuclear force.The electron is classified as a lepton, a fundamental partic...
An atom consists of three basic particles; positively charged protons, charge-less neutrons, and negatively charged electrons. The protons and neutrons are bound together in the center of the atom called the nucleus, and the electrons are held in orbit surrounding the nucleus....
In SSO, the motion of a particle during planar channeling will be one dimensional, and for electrons and positrons with energies up to several gigaelectron volt, it will be nonrelativistic, as in the hydrogen atom. potential from transverse coordinates. To determine the main characteristics of ...
Silicon carbide (SiC) and SiC/SiC composites are important candidate materials for use in the nuclear industry. Coarse grain models are the only tools capable of modelling defect accumulation under different irradiation conditions at a realistic time and length scale. The core of any such model is...
This work examines recent characteristic examples, in which the model has been employed in semiconductor and nuclear materials. Finally, there is a discussion on future directions and systems that will possibly be the focus of studies in the decades to come. 展开 ...
Explain the nuclear model of an atom? Why are electrons, rather than protons, the principal charge carries in a metal wire? There are very large numbers of charged particles in most objects. Why, then, don't most objects exhibit static electricity? Explain how rubbin fur on an ebonite ...
For each of the following three examples, explain how the molecules differ in the two different descriptions. A)Water at 70 C and water at 40 C B) A 5M glucose solution and a 6M glucose solution, both List and describe four differences between nuclear reactions and ordinary che...
ACTR and its complex with the nuclear coactivator binding domain of CREB binding protein is a frequently used model of the folding and binding mechanism characteristic of IDPs. It is likely that the binding interaction requires a preorganized conformation of ACTR in accordance with a conformer ...
