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.
30 is zinc's atomic number. 34 is selenium's.
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
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.
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.

32 electrons, an atom has the same amount of electrons as protons.

The atomic number is 30 because it is determined by the number of protons in the nucleus of an atom. Since the atom is neutral, it will also have 30 electrons surrounding the nucleus to balance the positive charge of the protons.
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 (???)
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.
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.
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.
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.
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.
