Structure 2.1—The ionic model: แบบฝึกหัด

What is the most likely formula for a compound formed between an element from Group 2 and an element from Group 16 of the periodic table?

Which of the following series shows the correct trend of increasing lattice enthalpy (more exothermic)?

Which of the following elements is most likely to form a cation with a charge of \(2+\)?

Which statement about the physical properties of ionic compounds is correct?

Which of the following substances contains only ionic bonding?

a) Explain the formation of an ionic bond between sodium (Na) and chlorine (Cl) atoms, referring to their electron configurations and the stability of the resulting ions.

b) Predict which compound, magnesium oxide ($$MgO$$) or sodium chloride ($$NaCl$$), will have a higher lattice energy. Justify your answer by considering the charges of the ions and their ionic radii.
