How do the number of protons in an atom's nucleus determine its atomic number?

• The number of protons in an atom's nucleus is equal to its atomic number
• The number of protons in an atom's nucleus is half of its atomic number
• The number of protons in an atom's nucleus is double its atomic number
• The number of protons in an atom's nucleus is unrelated to its atomic number
