What is the correct symbol for an ion containing 34 protons 44 neutrons and 36 electrons?
While the number nuclear protons as given is 34, and therefore we deal with the element selenium, there are 2 more electrons than protons, and therefore this species has an overall 2− charge. We represent this selenide ion as Se2− .

How do you find the total number of neutrons in an atom?
The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.
