Words that are synonyms are said to be synonymous, and the state of being a synonym is called synonymy. The word comes from Ancient Greek syn (ÏÏÎ½) (with) and onoma (á½Î½Î¿Î¼Î±) (name).
One magnesium atom and two chlorine atoms react to form one unit of magnesium chloride. This is because the magnesium atom has an oxidation number of -2 and each chlorine atom â¦ has an oxidation number of +1. 3 people found this useful.Answered.In Elements and Compounds.he formula unit for magnesium hydroxide is Mg(OH)2. This shows that in each formula unit there are two oxygen atoms, two hydrogen atoms, and one magnesium atom for a total of â¦ five atoms altogether. 5 people found this useful.
The ionic bond between magnesium and oxygen is stronger than the ionic bond between sodium and chlorine because of the greater charge on the ions. Magnesium oxide has a higher melting point because of the stronger bond.magnesium + oxygen magnesium oxide.agnesium is in group 2 of the periodic table. A magnesium atom will lose 2 electrons to form a stable 2+ ion. Oxygen is in group 6 of the periodic table. An oxygen atom will gain 2 electrons to form a stable 2- ion. In this example the electrons are shown as dots and crosses.
