Question

Расчитайте число протонов, злектронов и нейронов для атомов следующих изотопов: 57Fe и 58Fe

Answer 1

57Fe (26p, 26e, 31n) 

58Fe (26p, 26t, 32n)

Answer 2

Number of Protons, Electrons, and Neutrons in 57Fe and 58Fe Isotopes

To calculate the number of protons, electrons, and neutrons in the 57Fe and 58Fe isotopes, we need to understand the atomic structure of these isotopes.

57Fe Isotope: - The number 57 in 57Fe represents the atomic mass of the isotope, which is the sum of protons and neutrons in the nucleus. - The atomic number of iron (Fe) is 26, which represents the number of protons in the nucleus. - Since the atom is electrically neutral, the number of electrons is also equal to the number of protons.

To calculate the number of neutrons, we subtract the number of protons (atomic number) from the atomic mass:

Number of protons (Z) = 26 Number of electrons = 26 Atomic mass (A) = 57

Number of neutrons (N) = Atomic mass (A) - Number of protons (Z)

Let's calculate the number of neutrons for the 57Fe isotope:

Number of neutrons (N) = 57 - 26 = 31

Therefore, the 57Fe isotope has 26 protons, 26 electrons, and 31 neutrons.

58Fe Isotope: - The number 58 in 58Fe represents the atomic mass of the isotope. - The atomic number of iron (Fe) is 26.

Let's calculate the number of neutrons for the 58Fe isotope:

Number of neutrons (N) = Atomic mass (A) - Number of protons (Z)

Number of neutrons (N) = 58 - 26 = 32

Therefore, the 58Fe isotope has 26 protons, 26 electrons, and 32 neutrons.

In summary: - 57Fe isotope: 26 protons, 26 electrons, and 31 neutrons. - 58Fe isotope: 26 protons, 26 electrons, and 32 neutrons.
