Question
Silver oxide (Ag2O) is a black solid. It has a lattice structure.
Given this information, propose what you can say about how it is made up at the atomic level.
Solution
Silver oxide, Ag2O, is composed of silver and oxygen atoms. The fact that it is a solid and has a lattice structure tells us a few things about its atomic composition:
-
Arrangement of Atoms: In a lattice structure, atoms, ions or molecules are arranged in a highly ordered, repeating pattern extending in all three spatial dimensions. This means that the silver and oxygen atoms in Ag2O are not randomly distributed, but rather, they are organized in a specific, regular pattern.
-
Bonding: The lattice structure also suggests that the silver and oxygen atoms are bonded together. In the case of Ag2O, the bonds are likely ionic, given that silver is a metal and oxygen is a non-metal. Ionic bonds occur when electrons are transferred from one atom to another, resulting in positively charged and negatively charged ions that attract each other.
-
Ratio of Atoms: The chemical formula Ag2O tells us that for every 2 silver atoms, there is 1 oxygen atom. This ratio is maintained throughout the entire lattice structure.
-
Color: The black color of Ag2O could be due to the way the lattice structure absorbs and reflects light, which is a result of its electronic structure.
-
State of Matter: The fact that Ag2O is a solid at room temperature suggests that the forces between the atoms (ionic bonds in this case) are strong enough to hold them in place, relative to each other.
In conclusion, at the atomic level, silver oxide is made up of silver and oxygen atoms arranged in a regular, repeating pattern, bonded together through ionic bonds, in a 2:1 ratio, and the forces between these atoms are strong enough to maintain a solid state at room temperature.
