Question

two element X and Y have atomic number 12 and 16 to which period of the modern table do these two elements belongs what type of Bond will be formed between them and why also give the chemical formula of the compound formed​

Answer 1

The electronic configuration of element X is 2,8,2. Now, as it has 2 electrons in its outer most shell or in its valence shell. Therefore, it belongs to the period 3 (group 2) of the modern periodic table. The element is Magnesium (Mg). Similarly, the EC of element Y is 2,8,6. Now, as it has 6 electrons in its outer most shell or in its valence shell. Therefore, it belongs to the period 3 (group 6) of the modern periodic table. The element is Sulphur (S).

They will form ionic bond by sharing their electrons to complete their octets.

The chemical compound formed by them is MgS.

Answer 2

Answer:

2 period

They form ionic compounds because they are highly electronegative and electropositive.

Chemical formula=XY
