Group of answer choices
- NaCl
- CO2
- O2
- H2O

Solution
The substance that forms an ionic lattice instead of a molecule is NaCl (Sodium Chloride).
Here's why:
-
NaCl: Sodium (Na) is a metal and Chlorine (Cl) is a non-metal. When a metal and a non-metal combine, they form an ionic bond. In NaCl, Sodium loses an electron to become Na+ and Chlorine gains an electron to become Cl-. These ions then arrange themselves in a 3D structure known as an ionic lattice.
-
CO2: Carbon Dioxide is a molecule, not an ionic lattice. It consists of one Carbon atom double bonded to two Oxygen atoms.
-
O2: Oxygen is a diatomic molecule, meaning it consists of two atoms of the same element. It does not form an ionic lattice.
-
H2O: Water is a molecule, not an ionic lattice. It consists of two Hydrogen atoms bonded to one Oxygen atom.
