Question 2 — An element X has six - Questions at the end of the chapter - Chapter 9 - Atomic Foundations of Matter (Exploration)

Question 2
An element X has six electrons in its outer shell and forms a diatomic molecule. (i) Why would that be so? (ii) What kind of bond would it form? (iii) Draw the structure of the molecule it would form. (iv) A certain other element Y has two electrons in its second shell. Draw the structure of the molecule that X would form with Y.
View Answer Hide Answer
  • (i) With 6 valence electrons X needs 2 more, so two X atoms share electrons.
  • (ii) It forms a covalent (double) bond .
  • (iii) X=X, sharing two pairs (like O=O).
  • (iv) Y has 2 electrons in the second shell (needs... actually Y is like beryllium/helium-type); X shares with Y to complete shells — draw X—Y sharing as appropriate.
