 Electronic configuration of an atom is associated with the inner orbital structure of an atom. As many of you might have studied that an atom comprises a nucleus and energy orbitals around it in which electrons revolve around. while nucleus has neutrons as well protons which are basically positive charges; attracts electrons which are negative in nature towards the nucleus with a force called electrostatic force . This is the basic core idea of structure of an atom. Now, if we move a level further from this we will get to see that this is not just positive and negative charges being attracted to each other. Actually electrons that revolves around the nucleus in different orbitals are different energy levels and all of them combined defines the stability of a particular atom. Especially, we use the term electronic configuration to understand the energy status of an atom.  Like we have already said that electrons and protons are attracted by each other with electrostatic force...

Neet physics syllabus has been updated few times by NTA since 2023. Students find it challenging during their preparation time looking for the authentic neet physics syllabus. Because neither NTA nor any other trusted platforms provide the actual information about neet physics syllabus. There are certain chapters which are still recommended by NTA but CBSE as well as NCERT has officially deleted those chapters from the books. So for a student who is currently in 12th standard and preparing for NEET find it very troublesome. That's why we are here to provide you the most authentic and accurate neet physics syllabus for NEET UG 2027.  Best books for NEET Physics practical XI Best books for NEET Physics practical XII Updated NEET physics syllabus for 2027  Physics Syllabus (Class XI & XII) Remarks / Changes Units and measurements Same as before Kinematics Same as before Laws of motion Same as before Work energy power Same as before Gravitation Same as before Centre of mass Sa...

Consider a spring mass simple harmonic oscillator in one dimension. The mass of the particle is m kg and the spring constant is k N/m. At a given instant the extension of the spring is x meter and the speed of the particle is v m/s. On the x-v plane, if the graph of v as a function of x is a circle, then the correct option is A) k= m B) k= m^2 C) k= m^1/2 D) k= 1/m SHM Solution v 2 = ω 2 (A 2 - x 2 ) v 2 = k m (A 2 - x 2 ) ω 2 = k m v 2 = kA 2 m - kx 2 m kx 2 m + v 2 = kA 2 m — (i) Equation of a circle: x 2 + y 2 = R 2 — (ii) ∴ On com...

 NEET (National eligibility cum entrance test) which is the common entrance examination for admission in Medical, Dental, Homeopathy, Ayurveda, Veterinary, Nursing etc. courses in India. Previously this exam was conducted by CBSE. But from the year 2019 NTA (National Testing Agency) an organization was formed by the Indian Government to manage and conduct most of the India's national level entrance examinations like NEET, CUET, JEE MAINS, UGC NET etc. Since then NEET is being conducted every year by NTA.   As the governing authority of the examination has changed, the question pattern has also changed drastically over the period. When the exam used to be conducted by CBSE the paper difficulty was in moderate to difficult level. But NTA decreased the paper difficulty significantly to make the paper more generalized. And in the meantime the syllabus of NEET is changed several number of times.  According to some of the popular NEET educators, the paper difficulty of NEET 202...

Calculate emf of the cell given below: Pt(s)| H2(g, 2 atm)|HCl (aq,0.02 M) Eo H2/H+= 0V (Given: 2.303RT/F= 0.059, log2= 0.3010) A) 0.109 V B) 0.035 V C) -0.035 V D) -0.109 V For the given reaction: 1/2 H₂ + 1/2 Cl₂  ⟶ HCl + 1 e⁻   H₂ +  Cl₂   ⟶ 2 HCl + 2    e⁻ [ Balanced Equation] Now the question comes, what will be the value of emf? To determine the value of emf you just simply have to use the Nernst Equation mentioned in the Chapter Electrochemistry in Class 12 NCERT chemistry book, which is: Ecell = E⁰cell - 2.303RT/nF Log [product]/[reactant]  Ecell = - 0.059/2  Log[HCl]²/[ H₂ ] Given,  2.303RT/F = 0.059 Ecell = - 0.059/2    Log[0.02]²/[ 2 ]   [ E⁰cell = 0 V]     [n = No. of electrons]  Ecell = - 0.059/2   [ Log 2 x 10⁻⁴]   Ecell = - 0.059/2   [ Log 2 + Log10⁻⁴] Ecell = - 0.059/2   [ 0.3010 - 4]   ...

A rectangular wire loop of sides 8 cm and 3 cm with a small cut, is moving out of a region of uniform magnetic field of magnitude 0.3 T directed normal to the plane of the loop. The emf developed across the cut, if the velocity o f the loop is 2 cm s^-1, in a direction normal to the shorter side of the loop, will be A) 1.8 X 10^-4 volt B) 1.0 X 10^-4 volt C) 4.8 X 10^-4 volt D) 1.3 X 10^-4 volt   Solution

When 1 dm³ of CO2 gas is passed over hot coke, the volume of gaseous mixture after complete reaction at STP becomes 1.4 dm³. The Composition of the gaseous mixture at STP is A) 0.6 dm³ of CO, 0.8 dm³ of CO2 B) 0.8 dm³ of CO, 0.8 dm³ of CO2 C) 0.8 dm³ of CO, 0.6 dm³ of CO2 D) 0.6 dm³ of CO, 0.4 dm³ of CO2 Solution

'The Rattrap' a story written by Selma Lagerlof. And this piece of story is included in the class 12th CBSE syllabus. Here in this article the rattrap summary has been mentioned in a very interactive manner along with some commonly asked questions out of the rattrap summary. Imagine a cold, gloomy evening in the Swedish countryside. The wind howls through the trees, and a lonely vagabond trudges along the road. This man, a poor peddler, sells rattraps for a living, but deep inside, he harbors a cynical view of the world. He believes life itself is a giant rattrap, baiting people with riches and pleasures, only to ensnare them when they least expect it. The Peddler’s Struggle Life hasn’t been kind to this wanderer. He’s dressed in rags, barely making enough to survive. One day, he knocks on a cottage door, hoping for food or shelter. An old crofter (a poor farmer) welcomes him inside. The kind-hearted crofter, once a hard-working man at Ramsjö Ironworks, now lives alone with h...
