Solution

Electronic configuration of elements A (atomic number $= 17$ ) is $2, 8, 7$ and that of element B (atomic number $= 19$ ) is $2, 8, 8, 1$ . So, element B will lose one electron and element A will accept that electron to form a chemical compound.

The chemical formula of the compound formed by two of the above elements is “BA”.
