What is the charge on an ion formed by a Cs atom?

Cs also known as cesium has an atomic number of 55 which means it has 55 electrons. as well as having a Atomic Mass of 132, which means that there are 132 particles in the nucleus made up of protons and neutron, protons having a positive charge and neutrons having a neutral charge (no charge), electrons have a negitive charge that orbit the nucleus creating the atomic structure for Cs. hope this helped :D
