Question

Draw electron dot representation for the formation of magnesium oxide.

Answer 1

Hint:Calcination of Magnesium carbonate and magnesium hydroxide produced magnesium oxide. It is obtained by the process of magnesium chloride solution. Calcination occurs at different temperatures which produces magnesium oxide of different reactivity.

Complete step by step:
Magnesium burns in air with bright white light, giving off a large amount of energy, and white smoke is mostly magnesium oxide in very fine particles. The magnesium crumbles in white powder which is a mixture of magnesium oxide and magnesium nitride. Since air is a mixture of oxygen and nitrogen gases react with the magnesium metal.
Magnesium is able to bond with one oxygen atom. The formula of the compound is MgO. You can see the structure of MgO in dot structure that two atoms share four different electrons. When a bond is made with four electrons which is called a double bond.
The electron dot structure is shown as below:

Additional information:
Magnesium oxide dissolves to form an alkaline solution. Magnesium oxide contains charge species, it has no net charge, because it contains equal numbers of both ions. Magnesium oxide was shown to be an alkaline earth different from lime by the chemist Joseph black.

Note:Electron dot structures helpful tools in thinking about bonding. It represents the valence electron configuration around an atom. We will only consider dots placed around the chemical symbols. Electrons are placed up to two on each side of the element symbol for a maximum of eight, which is the number of electrons in a filled orbitals s and p shell.
