Detailed explanation-1: -Magnesium (Mg) is able to bond with one oxygen (O) atom. The formula of the compound is MgO. You can see in the dot structure that the two atoms share four different electrons. When a bond is made with four electrons, it is called a double bond.
Detailed explanation-2: -Group 17 elements (halogens) fluorine, chlorine, bromine, and iodine react with oxygen to form oxides. Fluorine forms two oxides with oxygen which are F2O and F2O2. Both fluorine oxides are called oxygen fluorides because fluorine is the more electronegative element.
Detailed explanation-3: –In the MgO molecule, the type of bond that is formed between Mg and O atoms is an ionic bond via the transfer of electrons.-Mg atoms have 12 electrons. Its electronic configuration is 2, 8, 2. Hence, Mg has 2 electrons in its valence shell which it wants to donate to achieve the noble gas configuration of Neon.
