34
There are 34 protons in a selenium-76 atom.
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
If you remove two protons from a germanium atom, it would become a selenium atom. This is because germanium has 32 protons, while selenium has 34 protons.
Number of protons in Selenium is 34.
The mass number of an atom is the sum of its protons and neutrons. Since selenium usually has 34 neutrons, an atom of selenium with 31 neutrons would have a mass number of 34 (31 neutrons + 17 protons).
Selenium's mass number is 79. It is the sum of the number of protons and neutrons in the nucleus of a selenium atom.
An atom of selenium-80 contains 34 protons, 46 neutrons, and 34 electrons. Protons and neutrons are located in the nucleus of the atom, while electrons orbit around the nucleus.
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.
There are 18 protons in an Aragon atom.
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.
An atom of selenium with an atomic number of 34 has 34 electrons. The mass number of 79 suggests that the total number of protons and neutrons in the nucleus is 79. Since the atomic number (protons) is given as 34, the number of neutrons can be calculated as 79 - 34 = 45.
