A synonym is a word or phrase that means exactly or nearly the same as another word or phrase in the same language. 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.
Ionic because in a dot diagram Magnesium has 2 valence electrons and chlorine has 7 valence electrons. With 2 chlorine atoms there are two spots for electrons to jump over bec â¦ ause each chlorine atom has room for one more electron and so both of magnesium's valence electrons would jump over to either chlorine.ovalent compounds are generally more soluble in organic solvents than in â¦ water, have a low melting point and do not conduct electricity well in water. Ionic compounds are formed when one or more electron are transferred from one atom to another. They stick together like magnets attract to each other.
