Beyond the Answer
The atomic mass of the element is approximately 159 atomic mass units (amu), derived from adding the protons and neutrons together (79 protons + 74 neutrons = 153). But since there are 80 electrons, we can subtract the mass of the electrons, leading to a practical mass nearer to 159 amu. The chemical symbol for the element is Au, which represents gold. It's fascinating to note that with 79 protons, this element occupies a prominent position, being highly valued both for its beauty and its historical significance in treasure and currency! The ionic charge of the element is +1. This arises from having 79 protons and 80 electrons, leading to an imbalance of one negatively charged electron, creating a positively charged ion (due to the excess of protons). It's like a superhero's origin story, where the extra proton transforms our element into a positively charged hero!
