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» Electronic configuration of element X, atomic number 12=2;8;2 Electronic configuration of element 'Y' atomic number 16=2,8,6 Both have three shells, so they belong to period 3. They will form an ionic bond as x will form electropositive ion and Y will form an electronegative ion.

Answer»

Electronic configuration of element X, atomic number 12=2;8;2

Electronic configuration of element 'Y' atomic number 16=2,8,6

Both have three shells, so they belong to period 3.

They will form an ionic bond as x will form electropositive ion and Y will form an electronegative ion.
