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.
The atomic number of an element is the number of protons in an atom's nucleus. Element with an atomic number 30 is Zinc (Zn), while element with an atomic number 34 is Selenium (Se).
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.
The atom contains 29 protons and 34 neutrons, which gives it an atomic number of 29(atomic number is the number of protons) and a mass number of 63 (sum of protons and neutrons). This corresponds to the element copper (Cu) with an atomic mass of approximately 63.5 amu.
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.
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 (???)
The atomic number of an element is the number of protons in an atom's nucleus. Element with an atomic number 30 is Zinc (Zn), while element with an atomic number 34 is Selenium (Se).
An atom with 32 protons will also have 32 electrons if it is electrically neutral. Electrons have a negative charge and balance out the positive charge of the protons in the nucleus.
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
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.
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.
The atom contains 29 protons and 34 neutrons, which gives it an atomic number of 29(atomic number is the number of protons) and a mass number of 63 (sum of protons and neutrons). This corresponds to the element copper (Cu) with an atomic mass of approximately 63.5 amu.
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
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.
