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.
The atomic number of selenium is 34. so there are 34 protons.
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.
around 30
Element 34, which is selenium, contains 2 protons less than krypton. Krypton has 36 protons, while selenium has 34 protons.
Selenium-79 is a radioisotope of selenium containing 34 protons and 45 neutrons.
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.
I don't know Se-50.
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.
