An unknown element contains 24 protons, 21 electrons,and has mass number 54
The atomic number of iron is 26 whereas the mass number of it is 56. Therefore it has 26 electrons and 30 neutrons (56-26).
The atomic number of iron (Fe) is 26. This means iron has 26 protons in its nucleus, determining its chemical properties and its place on the periodic table. The number 55.847 you provided is the atomic mass of iron, which is the weighted average mass of all isotopes of iron taking into account their relative abundance.
I am understanding you to mean an iron-57 ion with a charge of 3+.The atomic number of Fe is 26, which means that all Fe atoms or ions have 26 protons in their nuclei.In a neutral Fe atom, the number of electrons would be the same as the number of protons, which is 26. The charge on the Fe ion is 3+, which means the Fe atom has given up 3 electrons. So the number of electrons in an Fe3+ ion is 26-3, which is 23.The mass number of iron-57 = 57. The mass number is the sum of protons and neutrons in the atomic nuclei of iron-57 atoms. We know the number of protons is 26. The number of neutrons = mass number - the number of protons, which is 57-26 = 31 neutrons.To summarize:The number of protons in all Fe atoms is 26.The number of electrons in an any Fe3+ ion is 23.The number of neutrons in an iron-57 atom is 31.
The density of an element depends on the number of the nucleons (protons and neutrons) in the atom nucleus.
Iron atoms. Fe is the symbol for iron on the table of elements.
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
Number of protons + neutrons = mass number 26 protons + 31 neutrons 57
the protons will be the atomic number, in this case 26. The neutrons depends on which isotope. The most common isotope is iron-56, so that will have 30 neutrons. If the element is written in symbolic notation, the number on the top, minus the number on the bottom is the number of neutrons.
In the most abundant isotope of iron, there are 26 protons and 26 neutrons.
The element that has 26 electrons 29 neuetrons and 26 protons is Iron (Fe) The number of protons= electrons/atomic number
It varies. Iron is element 26 with a relative atomic mass of 55.85That means that the naturally occurring isotopes must have a range of neutrons.92% of iron atoms have 30 neutrons, 8% have 28 neutrons; 2% have 31 neutrons and there is a small percentage
The number of neutrons in an iron atom can vary depending on the isotope of iron. For the most common isotope, iron-56, there are 30 neutrons.
The proton number for an isotope of iron with 59 mass number would be 26, as iron has 26 protons in its nucleus. Since the mass number is 59 and the proton number is 26, the number of neutrons would be 33 (59 - 26).
Iron has 26 electrons; the number of neutrons is different for each isotope (number of neutrons = mass number - 26).
The atomic number of iron is 26 whereas the mass number of it is 56. Therefore it has 26 electrons and 30 neutrons (56-26).
It means that the atom being discussed is an isotope of iron that has a mass number of 57, which means that the atom has 31 neutrons.Added:It is the 3rd most abundant Fe isotope after Fe-56 and -54.
In a neutral iron (Fe) atom, the number of protons is 26, which is the atomic number of iron. The number of neutrons can vary, but the most common isotope of iron, Fe-56, has 30 neutrons. Since the atom is neutral, it will have an equal number of electrons as the number of protons, so it also has 26 electrons.
