The atomic number of an atom is determined by the number of protons it has. In this case, the atom has 13 protons, so its atomic number is 13.
The mass number is the sum of the number of protons and neutrons in the nucleus of an atom. Here, the atom has 13 protons and 14 neutrons, so the mass number is:
\[
\text{Mass number} = \text{Number of protons} + \text{Number of neutrons} = 13 + 14 = 27
\]
Therefore, the atomic number is 13 and the mass number is 27.
