Answer:
A) The arrangement of bonded atoms.
B) Number of Ionic bonds.
Explanation
The structural formula shows the bonding and general layout of the molecule.
Several molecules can have the same molecular formular especially in the branch of chemistry.
However each compound would always have a distinct way of bonding. By drawing out the structural formular of a molecule, we are pretty much just showing the arrangement of the bonded atoms. That is the primary detail in which a structural formular reveals.
Metallic bonds are generally bonds between metals and that can be obtained by checking if the compound has a metal.
Ionic bonds are bonds that result from the transfer of electrons between a metal and a non metal. By looking at the way the atoms are bonded, we can tell if that bond is an ionic or covalent. This is a secondary information revealed by the structural formula.
Shapes of Molecular orbitals are given by the molecular orbital diagrams and not the structural formular.
