Question

17
Two elements X and Y have atomic numbers 12 and 16 respectively. To which period of
the modem periodic table do these two elements belong? What type of bond will be
formed between them and why? Also give the chemical formula of the compound
formed.​

Answer 1

Answer:

Element X will belong to period 3

Element y will belong to period 3

They both will form ionic bond

Element X is magnesium and Y is Sulfur

magnesium can complete its octet by giving up those two valence electrons, becoming the magnesium cation.  Mg 2 + ,

Sulfur, which only needs two electrons to complete it octet, will pick up the two electrons coming from magnesium, becoming the sulfide anion,  S 2 − .

The electrostatic force of attraction will then bring the magnesium cations and the sulfur anions together   an ionic bond is formed.

Answer 2

Answer:

hope this answer will help you

Explanation:

both x and y belong to 3 period

x is mg

y is s

magnesium loses 2 electron to attain stability like a neon and becomes 2+ cation

sulphur gain 2 electron to attain stability like argon and becomes 2-anion.

so by transferring electron completely it will form ionic bond.

MgS
