Class 12 Physics Nuclei. Nuclear force. Nuclear force. The force with which the nucleons are bound together is known as nuclear force. It is the strong attractive force that binds the nucleons together. When the nuclear force is compared to other forces of nature like gravitational or coulomb's force etc.it is the strongest of all the forces All atomic nuclei except 1 H 1 are made of the protons and neutrons. A proton has a positive charge of the same magnitude as that of an electron, but a neutron is electric ally neutral. These protons and neutrons of an atom are collectively called nucleons of that atom Number of protons determines the atomic number of an element The mass of a proton is taken as one unit and equals to neutron. A proton is represented as 'p + ' Neutrons do not carry any charge and are neutral. Neutrons are present in the nucleus of all atoms, except hydrogen The mass of a neutron is taken as one unit and equals to that of proton Important Questions for Class 12 Physics Chapter 13 Nuclei Class 12 Important Questions Nuclei Class 12 Important Questions Very Short Answer Type Question 1.

  2. The positively charged protons tend to repel each other, and the neutrons help to hold the nucleus together. The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons
  3. The nuclear force is the force that binds the protons and neutrons in a nucleus together. This force can exist between protons and protons, neutrons and protons or neutrons and neutrons. This force is what holds the nucleus together. The charge of protons, which is +1 e, tends to push them away from each other with a strong electric field.
  4. Mathematically, we can say that a charge is the number of electrons multiplied by the charge on 1 electron. Symbolically, it is. Q = ne. where q is a charge, n is a number of electrons and e is a charge on 1 electron (1.6 × 10 -19 C). The two very basic natures of electric charges are. Like charges repel each other

  6. Electrons are negative. The reason for this is that the proton is positive. A proton attracts an electron by attracting each other by opposite charges, while two electrons repel each other. The polarity of the charge on an electron and a proton is thus shown to be the opposite

Some elements, such as carbon, potassium, and uranium, have multiple naturally-occurring isotopes. Isotopes are defined first by their element and then by the sum of the protons and neutrons present. Carbon-12 (or 12 C) contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 amu (six protons and six neutrons) The protons and neutrons are held together by the strong attractive forces inside the nucleus. These forces are called as nuclear forces.These forces, which act between the nucleons, are mainly responsible for the stability of the nucleus.Various characteristics of nuclear forces are given below F-ATPase, also known as F-Type ATPase, is an ATPase/synthase found in bacterial plasma membranes, in mitochondrial inner membranes (in oxidative phosphorylation, where it is known as Complex V), and in chloroplast thylakoid membranes.It uses a proton gradient to drive ATP synthesis by allowing the passive flux of protons across the membrane down their electrochemical gradient and using the. experimentwas carried out which led to the discovery of protons.

The mass of a proton is 1836 times the mass of an electron. Mass of a proton is 1.676 × 10-27 kg or 1.676 × 10-24 g. Number of protons in an atom possesses its atomic number. For example, hydrogen contains one proton, so its atomic number is 1 while helium contains two protons, so its atomic number is 2. Protons are spin -1/2 fermions

Discovery of Neutron. After the discovery of electron and proton Rutherford (1920) had predicted the existence of a neutral fundamental particle. In 1932, Chadwick bombarded the element Beryllium with a-particles and noticed the emission of a radiation having the following characteristics. The radiation was highly penetrating The mass of a proton or a neutron is about 1836 times greater than the mass of an electron. Protons and neutrons constitute the bulk of the mass of atoms. The discovery of the electron and the proton was crucial to the development of the modern model of the atom and provides an excellent case study in the application of the scientific method CBSE Class 12 Physics Question Paper 2019 - Class 12 exams are very important as it is one of the turning points of life because the field of higher studies is chosen after class 12.
