Question

This question has multiple parts. Work all the parts to get the most points What arguments would you use to convince another student in general chemistry that MgO consists of the ions Mg and O and not the ions Mg' and O? (Select all that apply.) The groups characteristically form ions with noble gas configurations; Group 2A loses two electrons and Group 6A gains two electrons. Look at other ionic compounds from the same groups; MgS and CaO. Calculate and compare A, H values for the two compounds Mg /O and Mg /O2. The Mg /O combination is more favorable thermodynamically Calculate and compare A, H values for the two compounds Mg /O and Mg /O. The Mg /O combination is less favorable thermodynamically.

second question: what experiments vould be done to provide some evidence that the correct formulation of the element above?

Answer 1

The correct argument for the above mention question would be that -

THE GROUPS CHARACTERISTICALLY FORM IONS WITH NOBLE GAS CONFIGURATION.GROUP 2A LOSES TWO ELECTRON AND GROUP 6A GAINS TWO ELECTRON.

The group 2A elements loses two electron from the s orbital to form stable nearest noble gas configuration.

the group 6A contains 4 electrons in the p orbitals and needs 2 electrons to form the nearest noble gas configuration.

Hence Mg loses two electrons which are accepted by the O to form Mg²⁺ and O^2-.

This two ions are attracted to each other and form MgO.
