The element Fe refers to iron. Here are the properties you requested:
Atomic number (Z): The atomic number represents the number of protons in the nucleus of an atom. For iron (Fe), the atomic number is 26.
Atomic mass (A): The atomic mass represents the total number of protons and neutrons in an atom's nucleus. The atomic mass of iron (Fe) is approximately 55.845 atomic mass units.
Number of electrons: In a neutral atom, the number of electrons is equal to the number of protons. Therefore, iron (Fe) has 26 electrons.
Number of protons: The number of protons in an atom is equivalent to the atomic number. As mentioned earlier, iron (Fe) has 26 protons.
Number of neutrons: The number of neutrons can be calculated by subtracting the atomic number (proton count) from the atomic mass. In this case, subtracting 26 protons from the atomic mass of 55.845 gives approximately 29 neutrons in an iron atom.
To summarize:
- Atomic number (Z): 26
- Atomic mass (A): 55.845
- Number of electrons: 26
- Number of protons: 26
- Number of neutrons: 29
