Answer- The above question is from the chapter 'Periodic Classification of Elements'.
Given question: Two elements X and Y have atomic number 12 and 8 respectively. Which type of Bond will they form ?
Write the formula of the compound formed by their combination ( in terms of x and y).
Answer: Element X has atomic number 12.
⇒ Its electronic configuration = 2,8,2
Its valency is 2. It can lose 2 electrons easily to become stable.
Thus, X is a metal.
Element Y has atomic number 8.
⇒ Its electronic configuration = 2,6
Its valency is 2. It can gain 2 electrons easily to become stable.
Thus, Y is a non-metal.
Metals and non-metals combine together to form an ionic bond.
Formula of their combination(by criss cross method) = X²⁺ Y²⁻ = XY
∴ X and Y will form an ionic bond.
The formula of their combination is XY.
