The Orthodox Church teaches that all bishops are equal. To be sure, there are different ranks of bishops (patriarch, archbishop, metropolitan, bishop); nevertheless, a bishop is a bishop. Such differences apply to the administration of a church or group of churches, not to the nature of the bishop.inally, Roman Catholicism teaches that the Holy Spirit proceeds from the Father and the Son  (filioque). In so doing, it spurned the Apostolic Tradition which always taught that God the Father is the single Source (monarchy) of the Son and the Spirit.
Chemical symbols. Each element is given its own chemical symbol, like O for oxygen and Cl for chlorine. Chemical symbols are usually one or two letters long, but sometimes three letters are used. Every chemical symbol starts with a capital letter, with the second or third letters written in lower case.For example, Mg is the correct symbol for magnesium, but mg, mG and MG are wrong.hemical symbols are usually one or two letters long, but sometimes three letters are used. Every chemical symbol starts with a capital letter, with the second or third letters written in lower case.
In order to make it easier to describe elements and molecules, chemical formulas are used. For example, H represents one atom of hydrogen and O represents one atom of oxygen. If we want to represent two atoms of hydrogen, instead of writing H H, we write H2.The subscript 2 means that two atoms of the element hydrogen have joined together to form a molecule.A subscript is only used when more than one atom is being represented. The graphic below illustrates the formula for water using symbols. Some more common molecules and their chemical formula.eview: 1  Chemical formulas are used to describe the types of atoms and their numbers in an element or compound. 2  The atoms of each element are represented by one or two different letters. 3  When more than one atom of a specific element is found in a molecule, a subscript is used to indicate this in the chemical formula.
