The element Fe corresponds to iron. Here's the information you requested:
Atomic number: The atomic number represents the number of protons in an atom's nucleus, which uniquely identifies the element. For iron (Fe), the atomic number is 26.
Mass number: The mass number is the sum of protons and neutrons in an atom's nucleus. Iron (Fe) has several isotopes, but the most common isotope is iron-56. The mass number of iron-56 is 56.
Electrons: In a neutral atom, the number of electrons is equal to the number of protons. Since iron (Fe) has an atomic number of 26, it also has 26 electrons.
Protons: The number of protons is the same as the atomic number. For iron (Fe), the atomic number is 26, so it has 26 protons.
Neutrons: To determine the number of neutrons, subtract the atomic number (protons) from the mass number. For iron-56, the mass number is 56, and the atomic number is 26. Subtracting 26 from 56 gives 30 neutrons.
So, for iron (Fe):
- Atomic number: 26
- Mass number: 56
- Electrons: 26
- Protons: 26
- Neutrons: 30
