The atomic number of iron ion is $\boxed{26}$ .

The atomic mass of an iron ion is $\boxed{56}$ .

The net charge on an iron ion is $\boxed{ + 3}$ .

Further Explanation:

The smallest particle that is the building block of matter is known as an atom. Most of the space in an atom is empty, and its mass is concentrated inside a small region called the nucleus.

An atom is written as $_{\text{Z}}^{\text{A}}{\text{X}}$ , where A is the mass number, Z is the atomic number and X is the letter symbol of the element.

Protons, electrons, and neutrons are the three subatomic particles that are present in the atom. The Protons and neutrons present in an atom are collectively called nucleons because these are located in the nucleus of the atom. Electrons revolve around the nucleus in definite orbits.

The positively charged subatomic particle is called proton. It is equal to the atomic number (Z) of the element.

Electron is the negatively charged subatomic particle. The number of electrons present in an atom is equal to the number of protons of an atom in a neutral atom.

The subatomic particle with no charge is called neutron. It is situated within the nucleus. The number of neutrons present in the nucleus of an atom is called the neutron number. Atomic mass or mass number is the total number of nucleons within the atomic nucleus. So if the atomic number or the proton number is known, the number of neutrons can be calculated by the difference of mass number (A) and atomic number (Z).

The ion of iron has 26 protons. As the number of protons is same as to the atomic number of the element. So the atomic number (Z) of iron is 26.

The expression to calculate the atomic mass of the element is,

${\text{Atomic mass}}\left({\text{A}}\right)={\text{Number of protons}}+{\text{Number of neutrons}}$ ......(1)

The number of protons in iron ion is 26.

The number of neutrons in iron ion is 30.

Substitute these values in equation (1) to calculate the atomic mass of iron.

$\begin{aligned}{\text{Atomic mass of iron}}&={\text{26}}+{\text{30}}\\&={\mathbf{56}}\\\end{aligned}$

The formula to calculate the net charge on the ion is,

${\text{Net charge}}={\text{Number of protons}}-{\text{Number of electrons}}$ ......(2)

The number of protons in iron ion is 26.

The number of electrons in iron ion is 23.

Substitute these values in equation (2) to calculate the net charge on the iron ion.

$\begin{aligned}{\text{Net charge on iron ion}}&=26 - 23\\&={\mathbf{ + 3}}\\\end{aligned}$

So the atomic number, atomic mass and net charge on iron ion are 26, 56, and +3 respectively.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
