Identify the incorrect statement and correct them.

  1. Like covalent compounds, coordinate compounds also contain charged particles (ions). So they are good conductors of electricity. 
  2. Ionic bond is a weak bond when compared to Hydrogen bond.
  3. Ionic or electrovalent bonds are formed by mutual sharing of electrons between atoms. 
  4. Loss of electrons is called Oxidation and gain of electron is called Reduction.
  5. The electrons which are not involved in bonding are called valence electrons.
संक्षेप में उत्तर

उत्तर

  1. Like covalent compounds, coordinate compounds also do not contain charged particles (ions), so they are bad conductors of electricity
  2. An ionic bond is formed by the electrostatic attraction between positive and negative ions. Hence it is stronger than Hydrogen bonding which is formed by electronegativity.
  3. The ionic bond is formed between two atoms when one or more electrons are transferred from the valence shell of one atom to the valence shell of the other atom. The atom that loses electrons will form a cation (positive ion) and the atom that gains electrons will form an anion (negative ion).
  4. Loss of electrons is called Oxidation and Gain of electron is called Reduction.
  5. The electrons which are involved in bonding are called valence electrons.
