1.
An ionic bond is formed primarily between:
Two non-metal atoms sharing pairs of valence electrons equally
Noble gas atoms at very low temperatures
A metal atom that loses electrons forming a cation and a non-metal atom that gains electrons forming an anion due to electrostatic attraction
Positive metal ions immersed in a sea of delocalized electrons
2.
Which of the following compounds exhibits polar covalent bonding due to a significant difference in electronegativity between 0.4 and 1.7?
Chlorine gas (Cl₂)
Methane (CH₄)
Sodium chloride (NaCl)
Water (H₂O)
3.
The nitrogen molecule (N₂) contains a:
Single ionic bond
Coordinate dative bond
Triple covalent bond (one sigma bond and two pi bonds) sharing 3 electron pairs
Double covalent bond
4.
Solid ionic compounds such as crystal NaCl do NOT conduct electricity in the solid state because:
Electrons are moving too rapidly
They contain no electrical charges
Their ions are tightly locked in fixed positions within the rigid crystal lattice and cannot move freely
They decompose in the presence of air
5.
A metallic bond is physically described as the electrostatic attraction between:
Positive metal cations in the crystal lattice and the mobile sea of delocalized valence electrons
Positive ions and negative non-metal anions
Dipole molecules in a polar liquid
Protons and neutrons in the nucleus
