1.
An ionic bond is formed primarily between:
Positive metal ions immersed in a sea of delocalized electrons
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
Two non-metal atoms sharing pairs of valence electrons equally
2.
Which of the following compounds exhibits polar covalent bonding due to a significant difference in electronegativity between 0.4 and 1.7?
Water (H2O)
Chlorine gas (Cl2)
Sodium chloride (NaCl)
Methane (CH4)
3.
The nitrogen molecule (N2) contains a:
Triple covalent bond (one sigma bond and two pi bonds) sharing 3 electron pairs
Coordinate dative bond
Double covalent bond
Single ionic bond
4.
Solid ionic compounds such as crystal NaCl do NOT conduct electricity in the solid state because:
They contain no electrical charges
They decompose in the presence of air
Electrons are moving too rapidly
Their ions are tightly locked in fixed positions within the rigid crystal lattice and cannot move freely
5.
A metallic bond is physically described as the electrostatic attraction between:
Protons and neutrons in the nucleus
Positive metal cations in the crystal lattice and the mobile sea of delocalized valence electrons
Dipole molecules in a polar liquid
Positive ions and negative non-metal anions
6.
Acids are chemical compounds that dissociate in aqueous solutions to produce:
Hydroxide ions (OH-) turning red litmus paper blue
Precipitated metallic salts
Sodium ions and chlorine gas
Hydrogen ions (H+ or hydronium ions H3O+), turning blue litmus paper red
7.
The chemical formula of aluminum sulfate is correctly written as:
AlSO4
Al2(SO4)3
Al(SO4)3
Al3(SO4)2
8.
Which of the following oxides is classified as an amphoteric oxide that reacts with both acids and bases to yield salt and water?
Carbon dioxide (CO2)
Sulfur trioxide (SO3)
Aluminum oxide (Al2O3)
Sodium oxide (Na2O)
9.
The reaction between an acid and a base to produce a salt and water is known as a:
Neutralization reaction
Combustion reaction
Thermal decomposition reaction
Polymerization reaction
10.

Weakly basic
Neutral
Strongly acidic
Strongly alkaline
