Question

How many neutrons does this atom have?

Iron chemical element stock illustration. Illustration of science - 107847587

a
82
b
26
c
30
d
55.845

Answer 1

mass number = number of protons + number of neutrons

mass number = ?
number of protons = 26
number of neutrons = mass number - 26
What's the mass number?

To determine the number of neutrons in an atom of iron, you need to know the atomic number and the atomic mass.

The atomic number of iron is represented by the symbol Z and is equal to the number of protons in the nucleus of an atom. In this case, the atomic number of iron is not provided.

The atomic mass of iron is represented by the symbol A and is equal to the sum of the protons and neutrons in the nucleus of an atom. The atomic mass of iron is given as 55.845, which means that an atom of iron has an atomic mass of 55.845 atomic mass units (u).

To find the number of neutrons, subtract the atomic number (Z) from the atomic mass (A).

Neutrons = Atomic Mass (A) - Atomic Number (Z)

Since the atomic number is not provided in the given options, we cannot determine the exact number of neutrons for this atom of iron.

To determine the number of neutrons in an atom, we need to subtract the atomic number from the atomic mass. The options provided are not clear, but we can calculate the number of neutrons based on the atomic mass of iron (Fe) if you confirm it. Can you please provide the atomic mass of iron?
