Question

An ion of iron has 26 protons, 30 neutrons, and 23 electrons. What are its atomic number, atomic mass,

hd net charge?
a. atomic number = 26, atomic mass= 56, not charge = 3+
b. atomic number = 26, atomic mass = 56, net charge = 3-
c. atomic number 30, atomic mass= 56, net charge = 3+
d. atomic number= 56, atomic mass= 26, net charge = 3-
3 protons, 4 neutrons and 3 electrons. What would be formed if one proton is

Answer 1

The iron ion has an atomic number of 26, an atomic mass of 56, and a net charge of 3+ due to it having 26 protons, 30 neutrons, and 23 electrons.

Step-by-step explanation:

The iron ion in question has 26 protons, which is its atomic number.

The atomic mass, also known as the mass number, is calculated by summing the number of protons and neutrons, resulting in 56 (26 protons + 30 neutrons).

To determine the net charge of the ion, we subtract the number of electrons from the number of protons (26 - 23), which gives us a 3+ charge because the iron ion has fewer electrons than protons.

Therefore, the correct answer is: atomic number = 26, atomic mass = 56, net charge = 3+.
