26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
Iron has 26 protons and electrons; the number of neutrons is different for each isotope:
Number of neutrons = Atomic Mass of the isotope - Atomic number of iron (26)
26 protons
26
Iron-56 has 26 protons, 30 neutrons, and 26electrons.
A neutral iron atom has 26 electrons. All iron atoms have 26 protons in their nuclei, which is why their atomic atomic number is 26. Protons have a positive charge, while electrons have a negative charge, so a neutral iron atom has 26 protons and 26 electrons.
23 electrons, 26 protons, 30 neutrons.
26 electron, the atomic number of the element in the periodic table tells us the number of electron in the neutral atom.
It doesn't matter if it's 56Fe or 49Fe; the number of protons in an atom of iron will remain constant. Why? Because if there was one more electron, it wouldn't be Fe anymore: it'd be cobalt (Co). The number of protons determines the element, the only thing that can change regarding the nuclear makeup of an atom without changing the element is the number of electrons. The 56 stands for the atomic weight of that particular isotope of iron. If each neutron and each proton weigh 1 amu each, then the atomic weight minus the number of protons will give you the number of neutrons.
(a) a sodium atom with 11 protons, 11 electrons, and 12 neutrons (b) a calcium atom with 20 protons, 18 electrons, and 20 neutrons (c) a helium atom with 2 protons, 2 electrons, and 2 neutrons (d) an iron atom with 26 protons, 26 electrons, and 30 neutrons
The number of protons, neutrons ad electrons is different.
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.
Iron-56 or 56Fe 56 protons makes it iron. If you add the protons and neutrons, you find the mass, which is 56.
26 It has 26 protons, 26 electrons and (mostly) 30 neutrons, but 28, 31 and 32 neutrons are natural isotopes of iron as well (though less than 10%).
Iron has 26 protons, and since protons and electrons are usually the same there are 26 electrons in Iron. There is 30 neutrons. So protons=26, electrons=26, neutrons=30.
An atom of iron would have pretty much the same subatomic particles as most other atoms - protons, electrons, and neutrons. Protons and neutrons are made up of more fundamental particles, quarks. The defining factor that makes it iron is that it would have 26 protons; in a neutral iron atom that would mean it would have 26 electrons. Different isotopes of iron might have differing numbers of neutrons, about 92% of iron is Fe-56 which has 30 neutrons.
Iron-56 has 26 protons, 30 neutrons, and 26electrons.
A neutral iron atom has 26 electrons. All iron atoms have 26 protons in their nuclei, which is why their atomic atomic number is 26. Protons have a positive charge, while electrons have a negative charge, so a neutral iron atom has 26 protons and 26 electrons.
From the periodic table, the atomic number of iron (Fe) is 26. This means that iron atoms have 26 protons in their nuclei. Mass number is the number of protons and neutrons in the nucleus of an isotope of an element. So, for your example of 31 neutrons, the sum of the number of protons (26) and neutrons (31) is 57. So the mass number of this iron atom is 57.
23 electrons, 26 protons, 30 neutrons.
It's definitely made of protons, neutrons, and electrons, in numbers that mark it most likely as an atom of either nickel or iron.
