6. Explain how you can use your knowledge of the atom's composition to determine the sign and magnitude of its charge (example: how does knowing the subatomic
particles of an atom help to determine that an atom will be +1).

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
