Concept Introduction:
Every element has a unique name and in most cases it was selected by the person who discovered it. For an element, abbreviation known as chemical symbol also exist for all elements name. Chemical symbol is simply one- or two-letter designation given for an element that is derived from the name of element. Chemical symbols occupy less space compared to chemical names.
In a chemical symbol, the first letter is always capitalized while the second letter is present in lower case. Two-letter chemical symbols are often the first two-letters of the chemical name of an element. Some elements symbol are derived from the Latin name of the element.

- Learning Goal: Atoms with the same number of protons but different numbers of neutrons are called isotopes. Some elements only have one naturally occurring isotope, while others such as carbon have two or more. In a naturally occurring sample, isotopes of each element are present in a certain percentage amount called the percent natural abundance. The mass number of an isotope is the sum of the number of protons and the number of neutrons for a particular isotope and is symbolized by A. A = number of protons + number of neutrons There are several different types of isotope notation. For example, a carbon isotope that has an atomic number of 6 and a mass number of 13 could be symbolized in any of the following ways: 13C, carbon-13, or C-13. b lock Part A Enter the appropriate symbol for an isotope of potassium-39 corresponding to the isotope notation X.
