(b) If the electrons lose energy continuously, the observed spectra should be continuous. NCERT Solutions for Class 11. n2 is greater than n1 by at least 1. (b) Discontinuous spectra: When gases or vapours of a chemical substance are heated in an electric arc or in a Bunsen ﬂame, light is emitted. Thus, a wave of higher frequency has a shorter wavelength while a wave of lower frequency has a longer wavelength. Chemistry Notes For Class 11 in Hindi and English Medium for exam preparation. m = e /(e/m) = – 1.6022 × 10-19/ – 1.7588 × 108 = 9.1096 × 10-28 g or 9.1096 × 10-31 kg. The notes on the structure of an atom have not only been prepared for class 11 but also for the different competitive exams such as iit jee, neet, etc. 4018Ar, 4019K, 4020Ca are known as isobars. We will also introduce a mobile app for viewing all the notes on mobile. Important characteristics of cathode rays are as follows: (a) Cathode rays are emitted from the surface of the cathode; their direction is not affected by the position of the anode. (f) Time period is the time taken by one wave to complete a cycle or vibration and is denoted by T. T = 1/ν. visible, ultraviolet, X-rays, etc. Structure of An Atom (Atomic Structure) Part 1. Also, the NCERT Chemistry Chapter 2 Structure of Atom Notes for class 12 is easy to read and includes all the study material, all clearly described and in a concise manner. The specific charge (e/m) of canal rays particles varied with the nature of gas and was found to be maximum if H2 was used. (d) Atoms of various elements take part in a chemical reaction to form compound (which is called molecule). Structure of Atom Class 11 Notes aims at increasing the self-confidence of the students by offering a simple way prepare for the chapter. Chemistry Notes for Class 11 Chapter 2 - Spectrum Spectrum is the continuous band or wavelength of light, irrespective of whether visible to the human eye or not. This type of spectrum that contains a lesser number of wavelengths in the emergent light than in incident light is called an absorption spectrum. The CBSE Class 11 Chemistry notes are created after careful analysis of past 10 years of examination papers and material by our panel of highly experienced teachers to cover all important topics in the entire NCERT Syllabus from Some Basic Concepts of Chemistry to Environmental Chemistry. When υ is equal to c, mass of the moving electron is infinity and when the velocity of the electron becomes greater than c, the mass of the electron becomes imaginary. Equilibrium Part -1 . ICSE - goyal brothers Thus, he pointed out that light has a wave as well as particle characteristics (dual nature). In this model, the atom is visualized as a pudding or cake of positive charge with raisins (electrons) embedded in it. We will keep adding updated notes, past papers, guess papers and other materials with time. Chapter 2. In view of the coronavirus pandemic, we are making LIVE CLASSES and VIDEO CLASSES completely FREE to prevent interruption in studies Our team is working continuously for the betterment of our students. When the radiations from a continuous source like a hot body (sunlight) containing the quanta of all wavelengths pass through a sample of hydrogen gas, then the wavelength missing in the emergent light gives dark lines on the bright background. A new theory which is known as the quantum theory of radiation was presented by Max Planck in 1901, to explain the blackbody radiation and photoelectric effect. Related Posts.

(d) For the emission of photoelectrons, the frequency of incident light must be equal or greater than the threshold frequency. Tips for preparing notes for Chemistry . These rays do not originate from the anode, and so it is wrong to call them anode rays. As a result, the electron will lose energy at every turn and move closer and closer to the nucleus following a spiral path and finally fall into the nucleus, thereby making the atom unstable. Thus, the electron which moves in an attractive field (created by protons present in the nucleus) will emit radiations. The emitted electrons are called photoelectrons. This spectrum consists of a limited number of lines, each of which corresponds to a different wavelength of light. NCERT Class 11 Chemistry Chapter 2 Structure of Atom Revision Notes contains very easy language which helps the students to study and revise syllabus with almost no time. Significance and development of periodic table. The energy of each photon of light depends on the frequency of the light, that is, E = hv. A major point of this model is that the mass of atom is considered to be spread uniformly over the atom. (d) The electrons revolve around the nucleus in closed orbits with high speeds.

In 1909, the first precise measurement of the charge on an electron was made by Robert A. Millikan using his oil drop experiment. Note: (i) Atoms give line spectra while molecules give band spectra. The concept of atomic theory of matter was put on firm footing by John Dalton with the atomic theory that was developed by him during the years 1803–1808. (b) The maximum kinetic energy of photoelectrons is directly proportional to the frequency of incident radiation; also, it is independent of the intensity of light used. (i) Cathode rays travel in straight line. (c) A very small number (about 1 in 20,000) did not pass through the foil at all but suffered large deﬂections or even rebound. (b) These consist of electric and magnetic fields that oscillate in directions perpendicular to each other and perpendicular to the direction in which the wave is travelling.

According to Einstein, the maximum kinetic energy of the ejected electron = Absorbed energy – Work function ½ mv2max = hν – hν0 = hc[1/λ – 1/λ0], where ν0 and λ0 are threshold frequency and threshold wavelength respectively. He observed that the produced penetrations were not affected by electric and magnetic fields. He also proposed the law of multiple proportions, as a logical consequence of his theory. Whenever an α-particle struck the screen, it produced a ﬂash of light. (b) Frequency is defined as the number of waves passing through a point in one second and is denoted by the symbol (nu) and is measured in terms of cycles (or waves) per second (cps) or Hertz (Hz). These rays were called cathode rays. Get CBSE Class 11 Chemistry chapter notes on ‘Structure of Atom’and learn about Atom, different atomic models, electromagnetic radiations, etc. In the mid-1800s, scientists (William Crookes 1879, Julius Plucker 1889) started to study the discharge of electricity through partially evacuated tubes.

These notes will surely save you time when stressful exam days. (b) The volume of the nucleus is very small and is only a very small fraction of the total volume of the atoms. The word atom in Greek means indivisible. Atom is made of electron, proton and neutrons. When a ray of this light is passed through a prism, a line spectrum is produced. Such atoms of the same element having the same atomic number but different mass numbers are known as isotopes. λν = 3 × 1010. (a) Most of the α-particles went straight without suffering any deﬂection. Dalton’s atomic theory (1808) is based on the following two laws: the law of conservation of mass and law of definite proportions. The charge on the electron was calculated to be – 1.6022 × 10-19 C. An electron has the smallest charge known; so it was, designated as a unit negative charge. 11 Chapter 11; 11th Class Chemistry Study Notes For those students, who have chosen their intermediate study career with Chemistry subject and are looking for the best ways to overcome the subjects, 11th class Chemistry study notes are prepared and uploaded here.
