Symbol of an atom that contains 7 protons and 8 neutrons has to be written. Concept Introduction: Each and every element present in the Periodic table has a unique name. Some of the elements are named considering their atomic number . In order to represent the elements in a short form, atomic symbols are used. Generally the first two letters of the element name will be used as symbol where the first letter is in upper case. Chemical names are represented as atomic symbols. In the symbols, the mass number and atomic number are shown. The complete symbol for an element can be represented as shown below. Atomic number is the total number of protons present in the atom of an element. Mass number is the total number of protons and neutrons present in nucleus of an atom.
