How do we find atomic mass?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu).
By adding together the number of protons and neutrons and multiplying by 1 amu
, you can calculate the mass of the atom.
What isotope has 17 protons and 17 electrons?
For example, every
chlorine
atom has 17 electrons and 17 protons; its atomic number is 17. However, three out of four chlorine atoms weigh 35 amu (17 protons and 18 neutrons) and the fourth weighs 37 amu (17 protons and 20 neutrons). These are the isotopes of chlorine.
How do you find the mass number?
Together, the number of protons and the number of neutrons determine an element’s mass number:
mass number = protons + neutrons
. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

What is the charge of an ion that contains 15 protons and 18 electrons?
Explanation: Protons are positively charged, while electrons are negatively charged. If the ion has 18 protons and 15 electrons, it has 3 more protons than electrons, therefore, the ion has an overall positive charge of
3+
.
What is the charge of an ion that contains 16 protons and 18 electrons?
Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 18 electrons, its net charge is
2–
