What does the number below each symbol represent?
The average Atomic Mass
The number placed below an elements symbol in a chemical formula is called a what?
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.
How you can easily identify elements from compounds through its chemical formula?
You can identify elements in a compound by looking at the chemical formula and noting the symbols of the elements present. Each element is represented by a unique symbol (e.g. H for hydrogen, O for oxygen). You can determine the number of atoms of each element by the subscripts next to the element symbol in the formula.
Why is the number placed below an element symbol in a chemical formula is called a subscript?
The number placed below an element symbol in a chemical formula is called a subscript because it indicates the number of atoms of that element in a molecule or compound. The subscript is written slightly below the element symbol to differentiate it from the coefficient, which applies to the whole molecule or compound.
Where does a subscript belong in a chemical formula?
A subscript belongs immediately after the symbol of an element in a chemical formula to indicate the number of atoms of that element present in the compound. It is written as a small number at the bottom right of the element's symbol.

What does the number below each symbol represent?
The average Atomic Mass
What does the circuit symbol below represent?
Switch
The number placed below an elements symbol in a chemical formula is called a what?
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.
The number below the symbol is the atomic?
The number below the symbol in the periodic table of elements is the relative atomic mass. It is calculated by taking the mass of all of the ions of an element and working out the mass based on the percentage occurrence of each ion.
What symbol is used to represent the Isle of Man?
A symbol with three legs joined together. See the link below.
Are the elements listed in order of atomic number or atomic mass?
The elements on the periodic table are listed in order of atomic number, which corresponds to the number of protons in the nucleus of each atom. The atomic mass of each element is typically listed below the element symbol and represents the average mass of the isotopes of that element.
What sumbol used for negative integers?
The symbol used for negative integers is the minus sign (−). It precedes a number to indicate that it is less than zero, such as in -3 or -15. Negative integers represent values that are below zero on the number line.

What are the first 20 elements of the periodic table and information about them?
Here they are listed by atomic number, element name and chemical symbol:1 Hydrogen H2 Helium He3 Lithium Li4 Beryllium Be5 Boron B6 Carbon C7 Nitrogen N8 Oxygen O9 Fluorine F10 Neon Ne11 Sodium Na12 Magnesium Mg13 Aluminum Al14 Silicon Si15 Phosphorus P16 Sulfur S17 Chlorine Cl18 Argon Ar19 Potassium K20 Calcium CaUse the link below to a list of all the chemical elements by atomic number. It's to the Wikipedia post, and each element is a hyperlink to the post on that element. Bookmark this bad boy, and the periodic table of elements at Wikipedia, too. The periodic table there is interactive, just like this list. And both are a boon to the study of school chemistry. Bookmark them for 30 days and try them out. You can always dump them later, but the benefits you'll derive in just one use will verify their worth. Promise.
