Define ionisation energy. How would the ionisation energy change when electron in hydrogen atom is replaced by a particle of mass 200 times that of the electron but having the same charge?
Ionization energy is the energy required to remove an electron from an atom in its ground state. Replacing the electron with a 200-times heavier particle would significantly increase ionization energy, as reduced mass and energy levels increase.

Two nuclei have mass numbers in the ratio 1: 2. What is the ratio of their nuclear densities?
The ratio of their nuclear densities is 1:1. Nuclear density is nearly constant for all nuclei because it depends only on the nuclear volume and not on the mass number, which scales proportionally with volume.

Define the binding energy of a nucleus.
The binding energy of a nucleus is the energy required to separate a nucleus into its constituent protons and neutrons. It reflects the stability of the nucleus, with higher binding energy indicating greater stability. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physiRead more

³₂He and ³₁H nuclei have the same mass number. Do they have the same binding energy?
No, ³₂He and ³₁H nuclei do not have the same binding energy. Although they have the same mass number, their nuclear structures and binding energies differ, as binding energy depends on proton-neutron interactions and nuclear stability.

Name the reaction responsible for energy production in the Sun.
The energy production in the Sun is primarily due to the proton-proton chain reaction. In this process, hydrogen nuclei fuse to form helium, releasing vast amounts of energy in the form of light and heat.
