Which of the statements below are true about subatomic particles?

1. It is possible to have an atomic number greater than the mass number.

2. All atoms with the same number of protons have the same atomic symbol.

3. The number of neutrons is equal to the mass number minus the atomic number.

4. An isotope (of the same element) has the same number of neutrons.

5. The number of electrons is equal to the atomic number minus the charge.

6. The atomic number equals the number of neutrons and protons.

7. The number of protons can be found to the bottom left of the symbol, the number of protons and neutrons to the upper left and the protons minus electrons to the upper right.
