1.	Two elements X and Y have atomic numbers 12 and 16 respectively. To which period of the modern periodic table do these two elements belong ? What type of bond will be formed between them and why?
Answer» Solution :Electronic configuration of element X, atomic number 12 = 2,8,2 Electronic configuration of element Y, atomic numbers 16 = 2,8,6 Both have three SHELLS, so they belong to period 3. They will FORM IONIC bond as X will form electropositive ion and Y will form electronegative ion.
