Q10. Highlight in the following colours the correct descriptions of: metallic bonds, covalent bonds and ionic bonds
A. Sharing of valence electrons
B. Magnetic dipole forces
C. Repulsion between ions being shielded by a valence electron cloud
D. Exchange of an electron between two atoms
E. Electrostatic attraction between a proton and the electron cloud of a F atom
Homework Answers
Metallic bonds: In a metallic bond there exists electrostatic forces between conduction electrons and positively charged metal ions (called as kernels). In a covalent bond valence electrons are shared between two atoms. In ionic bond one atom loses electron/s and the other gains electrons.
Answer: Metallic bonds- E. Electrostatic attraction between a proton and the electron cloud of a F atom
Covalent bonds: A. Sharing of valence electrons

Which of the following statements concerning double covalent bonds is correct? They are found only in molecules that contain S or O. They are found only in molecules that contain a coordinate covalent bond. They occur only between atoms containing 4 valence electrons. They always involve the sharing of 2 electron pairs.

Answer true or false. 1. Atoms that lose electrons to achieve a filled valence shell become cations and form ionic bonds with anions. 2. Ionic bonds tend to form between elements on the left side of the Periodic Table, and covalent bonds tend to form between elements on the right side of the Periodic Table. 3. Electronegativity is a measure of an atom's attraction for the electrons it shares in a chemical bond with another atom. 4. Fluorine, in the...
