Image A represents the structural formula, and only the structural formula allows the bond length of each bond between the atoms of the compound to be determined because it shows the bonds represented by a line.
Image B represents the structural formula, and only the structural formula allows the number of atoms of each element in the compound to be determined because it provides subscripts.
Image B represents the structural formula, and only the structural formula allows the number of atoms of each element in the compound to be determined because it provides subscripts.
Image B represents the structural formula, and only the structural formula allows the molecular shape to be determined because it shows the position and alignment of the atoms and bonds.
The correct choice is:
Image A represents the structural formula, and only the structural formula allows the type of bond formed by the compound to be determined because it shows the element symbols written in order (metals and then nonmetals).
Explanation:
The structural formula provides information about the arrangement and connectivity of atoms in a compound. It shows the element symbols written in order, indicating how the atoms are bonded together. For example, in the case of binary ionic compounds, the structural formula shows the metal element symbol first followed by the nonmetal element symbol. This allows us to determine the type of bond formed by the compound. In binary ionic compounds, the bond type is an ionic bond, which is formed between a metal and a nonmetal. The molecular formula, on the other hand, only provides information about the types and numbers of atoms present in the compound but does not give any information about the bond type or connectivity between the atoms. Therefore, the structural formula is essential for determining the type of bond formed by the compound.
