Number of protons in Selenium is 34.
There are 34 protons in a selenium-76 atom.
34
Selenium a non metal hexagonal grey element has 34 protons and electrons. The atomic structure of Selenium has 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
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
121
The element selenium (Se) has an atomic number of 34, which means it has 34 protons. The notation "80Se" indicates that this is an isotope of selenium with a mass number of 80, but the number of protons remains the same regardless of the isotope. Therefore, 80Se has 34 protons.

2 protons and 2 neutron
I don't know Se-50.
None. Protons and electrons are not constituents of a neutron. Both neutrons and protons are constituents of an atom's nucleus (core), while the electrons are situated in the electronic cloud around the nucleus.
