Final answer:
The atomic mass is 153, the chemical symbol is Au, and the ionic charge is 0.
Step-by-step explanation:
1. The atomic mass is calculated by adding the number of protons and neutrons together. So for the element with 79 protons and 74 neutrons, the atomic mass would be 79 + 74 = 153.
2. The chemical symbol of the element with 79 protons and 80 electrons would be the same as its atomic symbol, which is Au for gold.
3. To determine the ionic charge of an element, we need to know its electron configuration. Since the element has 80 electrons, we can assume that it is in its neutral state, meaning it has no overall charge. Therefore, the ionic charge would be 0.
