Atomic structure is an easy chapter with fairly simple concepts which students can grasp easily which makes it a student favourite, they can easily manage their time with these questions.
What is atomic structure in physics?
Atomic structure refers to the structure of an atom comprising a nucleus (centre) in which the protons (positively charged) and neutrons (neutral) are present. The negatively charged particles called electrons revolve around the centre of the nucleus.
What are the topics in atomic structure?
Atomic structure topics: Atomic models. Dual nature of Matter. Photoelectric Effect. Electromagnetic Radiations.
Is Class 12 chemistry difficult?
Chemistry is one of the more important and challenging subjects of CBSE Class 12 Science stream.
Is Class 12 chemistry enough for JEE mains?
Yes for JEE mains I can assure you if you read each and every topic of NCERT chemistry of class 11th and 12th then you can easily score between more than 70 in jee mains which is a good score.
Which is the toughest chapter in class 12 physics?
SHM, WAVES ( ELECTROMAGNETIC WAVES) , MODERN PHYSICS AND EMI are toughest topics in physics because it’s little bit hard to imagine these concepts in head.
Which is the easiest chapter in physics?
For PHYSICS : The easiest chapters among all the syllabus is the modern Physics, Radioactivity, kinematics( it is very scoring), Thermodynamics, waves and optics.
Which chemistry is toughest?
- Physical Chemistry is the hardest branch of chemistry.
- It involves the study of physical properties and constitution of matter, the laws of chemical combination, and theories governing chemical reactions.
What are atomic structures and its properties?
Each atom has its nucleus and the electrons bound to it. Protons and neutrons present inside the nucleus are known as nucleons. Mostly the nucleus is responsible as the major constituent for the mass of the atom. The structure of the atom mainly surrounds around electron, proton, and neutron.
What are the 5 atomic theories?
- Ancient Greek Beliefs.
- Dalton’s Atomic Theory.
- Rutherford’s Hypothesis.
- Bohr’s Theory.
- Einstein, Heisenberg and Quantum Mechanics.
What are the 5 parts of atom?
Each of these parts has an associated charge, with protons carrying a positive charge, electrons having a negative charge, and neutrons possessing no net charge. In accordance with the Standard Model of particle physics, protons and neutrons make up the nucleus of the atom, while electrons orbit it in a “cloud”.
What are the 3 types of atoms?
Atoms consist of three fundamental types of particles, protons, electrons and neutrons. Neutrons and protons have approximately the same mass and in contrast to this the mass of an electron is negligible. A proton carries a positive charge, a neutron has no charge and an electron is negatively charged.
Are there 118 types of atoms?
There are only about 118 different kinds of atoms, but millions of compounds.
What are the three types of atomic structure?
Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
Can I prepare chemistry in 2 days?
HI, It is not really possible to cover up all chemistry syllabus in just 2 days. You must have revised it before and then you can revise in 2 days. Basically in 2 days you can focus on previous year papers, Revise NCERT for must.
How do you get 90% in chemistry?
To score above 90 marks in chemistry, practising CBSE Class 12 sample papers are essential. Through these students can analyse their exam preparation. Solving the previous year’s class 12 Chemistry question papers will provide students with an idea of the exam pattern and type of questions asked in the exam.
Is 12th easier than 11?
No, both are same level. If you are in class 11th with conceptually, then you do have to face problem in class 12th. You will find class 12th syllabus easier as compare to class 11th.
Can I crack JEE With only Class 12?
No, it is almost impossible to crack JEE by studying class 12 syllabus only. JEE paper gives equal weightage to class 11 and 12 syllabus with a slight variation here and there.
Which is tough 11th or 12th for JEE?
Finding something “tough” is a very relative concept whether it’s class 11 or class 12 JEE syllabus. Students coming to class 11 find it a bit difficult as there is a major shift in the syllabus which requires logical learning and analytical thinking. Compared to that, they find class 12 a bit easier than class 11.
Does 12 marks matter in IIT?
Class 12 marks have no weightage in the preparation of JEE Main ranks. Students should know that the ranks will be determined based on their score in the entrance exam. However, for admission into IITs, NITs, CFTIs the score that candidates have secured in their class 12 board exam will be taken into account.
Which physics is most difficult?
Quantum mechanics is deemed the hardest part of physics.
What is the hardest year 12 subject?
What are the 12 Hardest A-Level Subjects? The 12 hardest A-Level subjects are Mathematics, Further Mathematics, History, Chemistry, Biology and Physics. The list also includes English Literature, Art, Psychology, Computer Programming and Music. You might be looking at some of these subjects and thinking, “No way!
Which is the hardest branch of physics?
Atomic Physics is considered one of the hardest branches of Physics.
Is Class 12 PHY hard?
The CBSE Class 12 Physics paper was moderately difficult but a little lengthy as per feedback from teachers and students. The CBSE Class 12 Physics paper was of moderate difficulty but a little lengthy as per experts. It was not too tough but questions were mostly conceptual.
Is 12th physics is easy?
Most of the students find the Class 12 Physics subject difficult. This is also due to the vast syllabus and derivations that are there in both parts of the NCERT class 12 Physics book.
