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.
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
How many neutrons would be present in the nucleus of an atom of selenium-76?
Selenium-76 has an atomic number of 34, which means it has 34 protons in its nucleus. To find the number of neutrons, you subtract the atomic number from the mass number. The mass number of selenium-76 is 76, so the number of neutrons would be 76 - 34 = 42 neutrons.
How many protons and neutrons does selenium have?
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.
What is the atomic mass and symbol of an element with 34protons 33 neutrons 34 electrons?
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
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.
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
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.
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 nuetrons does selenium have?
Neutrons = Mass number (Se-80) minus Atom (or proton 34Se) number (34) = 80-34 = 46 neutrons
What is the sum of protons and neutrons in an atom?
Mass number!:)
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
How many neutrons would be present in the nucleus of an atom of selenium-76?
Selenium-76 has an atomic number of 34, which means it has 34 protons in its nucleus. To find the number of neutrons, you subtract the atomic number from the mass number. The mass number of selenium-76 is 76, so the number of neutrons would be 76 - 34 = 42 neutrons.

What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
Is the number of neutrons in an atom known as its mass number?
No, neutrons + protons = mass
What is the atomic mass and symbol of an element with 34protons 33 neutrons 34 electrons?
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
