a. You determine element by the number of protons the element has. Let's first find that: What do you know? Mass number : 65 Neutron number: 35 If mass number is Protons + Neutrons, we can find # of protons through subtracting: 65 - 35 = 30 Protons. Look on your periodic table. Which element has 30 protons? (30 is also the atomic number if that helps). b. Charge is the difference between negative electrons and positive protons, right? Because we know the numbers for both, this is easy: 28 electrons compared to 30 protons 30 - 28 = 2 difference Since there are more protons, you would have a positive charge of 2. :)
