(i) Write the electron dot structure for sodium, oxygen and magnesium.
(ii) Show the formation of `Na_(2)O` and `MgO` by the transfer of electrons.
(iii) What are the ions present in these compounds.

Explanation

(a) Magnesium and Manganese
(b) Formation loses twon electrons , and forms Magnesium ions to complete its octet.
`Mg rarr Mf^(2+) +2^( e )`
oxygen gains that two electrons to becomes `o^(2-)`
`Mg^(2+) +O_(2) rarr MgO`
