What is the mass number of a selenium atom that has 31 neutrons?
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).
How many protons neutrons and electrons are in a selenium 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
What is selenium's mass number?
Selenium's mass number is 79. It is the sum of the number of protons and neutrons in the nucleus of a selenium atom.
What particles make up an atom of selenium-80?
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.
How many nuetrons does selenium have?
Neutrons = Mass number (Se-80) minus Atom (or proton 34Se) number (34) = 80-34 = 46 neutrons
How many neutrons in selenium?
45
How many neutrons are in selenium-76?
A simply formula is the atomic mass of selenium (rounded to the whole number) - atomic number = neutrons. So Selenium 76 has 45 neutrons.
How many does electron protons and neutrons does selenium have?
Selenium a non metal hexagonal grey element has 34 protons and electrons. The atomic structure of Selenium has 45 neutrons.
How many electrons are in an atom of selenium with a mass number of 79 and an atomic number of 34?
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.
What is the number of neutrons and electrons in selenium?
Slenium has 34 protons and 45 neutrons! :)
How many protons in selenium 76?
There are 34 protons in a selenium-76 atom.
How many protons neutrons and electrons does selenium-55 have?
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
