NCERT Solutions for Class 11 Chemistry Chapter 2: Points to Remember

We have provided a few important points that are covered in NCERT Class 12 Maths Chapter 7 Integrals to help students in their exam preparations. Refer to the points below:

  • Atom is made up of electrons, protons and neutrons called fundamental particles.
  • Electron was discovered by J. J. Thomson from study of cathode rays.
  • Mass of electron = 9.11 × 10−31 kg = 1/1837 th of that of H-atom.
  • Charge on electron = 1.602 × 10−19 coulomb.
  • e/me = 1.758820 × 1011 C Kg−1
  • Proton was discovered by Goldstein from study of anode rays using a perforated cathode in the discharge tube.
  • Neutron was discovered by Chadwick by bombarding Be or B atoms with α-rays.
  • Atomic number (Z) = number of protons in the nucleus of an atom = number of electrons in a neutral atom
  • Mass number (A) = number of protons (Z) + number of neutrons (n)
  • Atoms of the same element having the same atomic number but different mass numbers are called isotopes.
  • Atoms of different elements having different atomic numbers but same mass number are called isobars.
