Answer:
The answer to your question is: +89
Explanation:
Actin has a atomic number of 89, that means that it has 89 protons in its nucleus.
Inside the nucleus are found protons and neutrons, neutrons do not have any charge whereas protons are positively charge, so if we only consider the charge inside the nucleus it will be +89.
It also has 89 electrons that are negatively charged, but they are not in the nucleus.
