The equation shows the reaction between element X and dilute hydrochloric acid: X(s) + 2HCl(aq) -> XCl2(aq) + H2(g) What types of bonding is present in element X and in compound XCl2?
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions. The element X is metal as Metals react with halogens to form salts.The compound XCl2 is a salt and has ionic bonds. As two chlorine atoms are attached, this shows the central metal has two valence electrons in free states, so it is a metal of group II A[Be, Mg, Ca, Sr, Ba].

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
