A stable molecule can be formed using 1 magnesium, 2 oxygens and 2 hydrogens. Looking at the number of electrons in the outer shell of each of these elements, can you determine how these elements can share electrons (covalent bonds) or transfer an electron (ionic bond) to form a stable molecule with the formula MgO2H2. Note: ionic bonds and covalent bonds can both be present in the same molecule. Draw a molecule that could be made using these elements and...
