The atomic number of selenium is 34. So there are 34 protons.
In Se-80, there will be 46 neutrons (80 - 34 = 46)
Note: There is no isotope Selenium-30 as originally asked in the question.
This isotope is shown in hyphen notation: on the left side of the hyphen is the isotope's name, and on the right side is the isotope's mass number. The mass number of an element is the total number of particles in the nucleus (the number of protons + neutrons an atom has).
In order to get the number of protons an atom has, find its atomic number on the Periodic Table. Selenium's atomic number is 34.... wait, this doesn't make any sense. If it has a mass number of 30 and an atomic number of 34, it has -4 neutrons.
I'm sorry, but it looks like you have the problem wrong.
34 protons, 45 neutrons, and 34 electrons
34 protons neutrons and electrons
Selenium-30 doesn't exist.
Selenium a non metal hexagonal grey element has 34 protons and electrons. The atomic structure of Selenium has 45 neutrons.
Selenium-79 is a radioisotope of selenium containing 34 protons and 45 neutrons.
Selenium (Se) has an atomic number of 34 which means in a balance atom Se will have 34 protons and 34 electrons then Se has a mass of 79 so to get the neutrons we minus the protons from the mass and we get 45 final answer: Neutrons: 45 Protons:34 Electrons: 34
The atomic number of selenium is 34. so there are 34 protons. Number of neutrons = 80 - 34 = 46
I don't know Se-50.

Slenium has 34 protons and 45 neutrons! :)
Selenium is an element which contains 34 protons. With these 34 protons, it also contains 45 electrons. SE (selenium's symbol) is mainly used TV cameras and photoelectric cells. The element was discovered in 1817 by Jons Berzelius.
Number of protons in Selenium is 34.
Since an alpha particle is simply two protons and two neutrons bound together, or He2+, the alpha decay of selenium-78 is easily determined. Selenium-78 has 34 protons and 44 neutrons. Subtract 2 from each of these due to the loss of the alpha particle and you have 32 protons and 42 neutrons. This new atom is germanium-74.
protons=5 neutrons=10 electrons = 34
45 neutrons
