Answer: Fe+2
Step-by-step explanation:
You have to take in account of the atomic number, mass number, and net charge:
The atomic number: The number of protons in the nucleus of an atom
Net Charge of atom: Overall charge of atom
The atomic number of Iron is 26.
The atomic mass is 56.
The net charge of an ion of iron is +2 (a cation)
The atomic mass of iron is 56.
All atoms are made up of subatomic particles: protons, and neutrons (part of the nucleus.) Electrons revolve around them, and are negatively charged. Protons are positive, and neutrons are negative.
In this case, an ion of iron has an 26 protons. Then:
Atomic number = number of protons= 26
The atomic number of iron is 26.
On the other hand, the mass number or atomic mass tells us the total number of particles in the nucleus. The mass number is the sum of the number of protons and the number of neutrons in the atomic nucleus:
Mass number = (number of protons) + (number of neutrons)
In this case, an ion of iron has an 26 protons and 30 neutrons. Then:
Mass number = 26 + 30
Mass number= 56
So, the atomic mass of iron is 56.
An ion is an atom or group of atoms with an electrical charge. Ions with a positive charge are called cations, while those with a negative charge are called anions. There is an imbalance between electrons, and protons.
The neutron is an electrically neutral subatomic particle, while the proton has a positive electrical charge. Electrons have a negative electrical charge.
So, the net charge of an atom or body is a function of the number of protons and electrons, and it is the algebraic sum of charges. In this case:
net charge= 26 positives electrical charges + (-24) negative electrical charge
net charge= 26 - 24
net charge= +2
Finally, the net charge of an ion of iron is +2 (a cation)
The Symbol would be Fe+2
