(a)
Interpretation:
The number of covalent bonds and the lone pairs of electron in the molecule formed by reaction between given atoms is to be drawn by using electron-dot symbols with lines showing as covalent bonds.
Concept introduction:
Covalent bonds are formed by sharing of electrons between atoms.
The valence electrons of Aluminum are 3 electrons.
The valence electrons of Bromine are 7 electrons.
