Answer:

Explanation:

⇒  Number of given elements are 8. They are A,B,C,D,E,F,G and H.

⇒  All 8 elements are belongs to same period because they have same number of electronic shells and have different number of electrons in the outermost shell.

⇒  We can see the above pattern in 3  

rd

 period as it have 8 elements.

⇒  Nature of compound formed by a combination of element B and F is ionic in nature since B is metal and F is non-metal.

⇒  Here ⇒ A=Na (Sodium), B=Mg (Magnesium),

                    C=Al (aluminium), D=Si (Silicon),

                    E=P (Phosphorus), F=S (Sulphur),  

                    G=Cl (Chlorine), H=Ar (Argon).
