Final answer:
The atomic mass of the element is 96. The chemical symbol is Mo. The ionic charge is 1+.
Step-by-step explanation:
1. The atomic mass of an element is the sum of the number of protons and neutrons. In this case, the element has 42 protons and 54 neutrons, so the atomic mass is 42 + 54 = 96.
2. The chemical symbol of an element with 42 protons is Mo. Mo is the symbol for Molybdenum.
3. The ionic charge of an element is determined by the number of electrons it has compared to its number of protons. Since this element has 42 protons and 41 electrons, it has a 1+ ionic charge.
