NCERT Solutions for Class 11 Chemistry Chapter 3: Points to Remember

Students can find the important points related to Class 11 Chemistry Chapter 3 as mentioned below:

• Dobereiner’s triads: When three elements of a triad were arranged in order of increasing atomic weights, the atomic weight of the middle element was either nearly the same or the atomic weight of the middle element was approximately the arithmetic mean of the other two.
• Newlands law of octaves: When lighter elements were arranged in order of their increasing atomic weights, the properties of every eighth element were similar to those of the first like the eighth note of a musical scale.
• Lother-Meyer plotted a graph between atomic volume of the elements against their atomic weights. He observed that the elements with similar properties occupied similar positions on the curve.
• Mendeleev’s period law states that physical and chemical properties of elements are a periodic function of their atomic weights.
• Modern periodic law states that physical and chemical properties of the elements are a periodic function of their atomic numbers.
• Modern periodic table is also called long form of the periodic table or Bohr’s table.
• Atomic radius is the distance between the centre of the nucleus to the outermost shell containing electrons.
• Covalent radius is one-half the distance between the nuclei of two covalently bonded atoms of the same element in a molecule.
• van der Waals radius is one-half the distance between the nuclei of two adjacent identical atoms belonging to two neighbouring molecules of an element. It is also called inert gas radii.
• Metallic radius is one-half the internuclear distance between the two adjacent metal ions in the metallic lattice.
• Periodicity of Valence: The valence of representative elements is usually equal to the number of electrons in the outermost orbitals and/or equal to eight minus the number of outermost electrons.
• Some elements of the second period show a diagonal relationship with elements of the third period and hence exhibit some similar properties.
