You are asked to write the atomic symbol for an atom.
You are given the number of protons, neutrons, and electrons in the atom.
a. ^{15}_{7}N. The atomic number of nitrogen is equal to the number of protons (7), and the mass number is equal to the number of protons plus the number of neutrons (7 + 8 = 15).
b. ^{235}_{92}Au. The atomic number of uranium is equal to the number of protons (92), and the mass number is equal to the number of protons plus the number of neutrons (92 + 143 = 235).
