The discrete symmetries parity, charge conjugation and time reversal are at the core of the Standard Model, which describes all confirmed observations in experiments. The interference between the three forces and three generations of particles lead to a variety of experimental observations of violations of these symmetries, such as parity violation or CP violations. Any measurement of such a violations in atomic parity experiments or searches for permanent electric dipole moments provides stringent limits on additional particles or forces. Rare isotopes as they are available at CERN ISOLDE open a wider range for selecting the ideal atomic system to study such effects. Here isotopes of the heavy alkaline earth metal radium exhibit optimal properties for an unprecedented quantitative measurement atomic parity violation. This experiment relies on the state of the art technology of single ion optical clocks and the well understood atomic structure of such elements. We will discuss the experiment with a single trapped barium ion at the Van Swinderen Institute of Particle Physics and Gravity of the University of Groningen in order to describe the road towards a measurement of atomic parity violation in a single trapped Ra+ ion. This particular measurement enables, e.g., an at least fivefold improvement in accuracy of sin2(θWeinberg ) at low momentum transfer.
