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 does the nucleusof a of a copper atom compare to the nucleus of a nickel atom?
Comparison of nucleus of Cu atom and Ni atom: Cu atom has 29 protons and 34 neutrons. A Ni atom has 28 protons and 31 neutrons.
What is the identity and atomic mass of an atom containing 29 electrons 34 neutrons and 29 protons?
This is a single specific isotope of copper (element 29). The isotope 63Cu makes up about 70% of the copper on Earth, and most of the remaining 30% is the 65Cu isotope. The isotope 64Cu is also known, but this atom is not stable, having a half-life of just 12.7 hours.
How many neutrons would be present in the nucleus of an atom of selenium-76?
All selenium atoms have 34 protons, because that is what defines Selenium. The number that comes after an isotope name is the mass number, which is the sum of the protons and neutrons. Because we know the sum of the protons and neutrons, and the number of protons, we can easily deduce the number of neutrons.p=# of protons n=# of neutrons, and mn=mass numberp+n=mnn=mn-pn=(76)-(34)n=42
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.
If an atom has 34 protons and 40 neutrons what is its atomic number?
The mass number is the sum of the number of protons and neutrons in the nucleus of the atom which is 74. Alternative answer 58 is the answer (???)
How many electrons are in an atom that has 32 protons?
32 electrons, an atom has the same amount of electrons as 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

How many protons does an atom of copper have?
A copper atom has 29 protons in its nucleus. The number of protons of an atom is equal to the atomic number of the element in the periodic table.Copper's atomic number is 29, so a copper atom contains 29 protons.Atomic number = number of protons.It contains 29 electrons,29 protons and 34 neutrons.As copper is element number 29, it has 29 protons. The proton number is the same as the element number shown in the periodic table.

How many protons are in a selenium atom?
34
How many protons are present in an atom which has an atomic number of 34?
34
How many protons and neutrons does selenium have?
The atomic number of selenium is 34. So there are 34 protons. In Se-80, there will be 46 neutrons (80 - 34 = 46) Note: There is no isotope Selenium-30 as originally asked in the question.
Which atom composed of 16 protons 16 electrons and 16 neutrons?
The atomic number of an element is invariably the number of protons in its nucleus. So, 16.
