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

We have provided a few important points that are covered in NCERT Class 11 Chemistry Chapter 2 Structure of Atoms. Students can refer to the points for a quick revision to recall important concepts.

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/m_e = 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.
