Verified step by step guidance

1. Understand that in the periodic table, each element is represented by a box containing specific information.
2. Recognize that the symbol 'Mn' is the chemical symbol for the element manganese, which is a shorthand notation used universally to represent the element.
3. Note that the atomic number is usually a number located above or near the symbol, indicating the number of protons in the nucleus of the atom.
4. Identify that the atomic mass is typically a decimal number located below the symbol, representing the average mass of the element's isotopes.
5. Conclude that the symbol 'Mn' itself specifically indicates the chemical symbol for manganese, not the atomic number, atomic mass, or electron configuration.
