The atomic number Z is the number of protons in the nucleus of an atom of an element Each element has a unique number of protons. For example, an atom with 47
protons is always a silver atom and has an atomic number of 47. The atomic number is used to distinguish different elements from one another.
The mass number A is the sum of the number of protons and neutrons in the nucleus of an atom of an element. Atoms that have the same atomic number but different
mass numbers are called isotopes. For example, all atoms with atomic number 6 are carbon atoms, but carbon atoms with mass numbers of 12 and 13 are isotopes of
one another.
Each element is assigned a unique chemical symbol. For example, the symbol for hydrogen is H, and the symbol for oxygen is O. Some elements have symbols based
their names in languages other than English. For example, the symbol for iron is Fe, which is based on the Latin ferrum.
The atomic number, mass number, and chemical symbol are often combined to describe a given atom. For example, an atom of lithium (Li) with atomic number 3 and a
mass number of 7 could be written Li Since the atomic number and the symbol are both unique to a given element, the atomic number is often left off of this notation,
leaving Li.
