I think it might be Nitrogen dioxide, but please check behind
The balanced equation :
8Al + 3Fe₃O₄→ 4Al₂O₃ + 9Fe
You just have to look for which element is in bold because the question is not clear

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:
1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.
2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product
3. Select the coefficient of the substance with the most complex chemical formula equal to 1
Reaction
Al + Fe₃O₄→ Al₂O₃ + Fe
give a coefficient
aAl + Fe₃O₄→ bAl₂O₃ + cFe
O, left=4, right=3b⇒3b=4⇒b=4/3
Al, left=a, right=2b⇒a=2b⇒a=2.4/3⇒a=8/3
Fe, left=3, right=c⇒c=3
The equation becomes :
8/3Al + Fe₃O₄→ 4/3Al₂O₃ + 3Fe x3
8Al + 3Fe₃O₄→ 4Al₂O₃ + 9Fe
They are in order according to their atomic number, so the position should tell you the atomic number.
Democritus was the first to propose the idea of the atom. He said the atom was just this tiny, solid sphere. However, he used no scientific evidence to support his claim, so a guy named John Dalton did some experimenting and basically backed up Democritus' claim with evidence. Then, a guy named J.J. Thompson came along and said the atom was not solid and that is consisted of tiny negatively charged particles(electrons) and he came up with the Plum Pudding model which is just a tiny sphere with a punch of random scattered dots in it. After that, Ernest Rutherford did experiments and found that the tiny sphere is made up of mostly empty space with a tiny, dense, positively charged sphere inside of it, and the negatively charged particles just randomly float around it. Neils Bohr then said that the electrons take specific, circular, evenly spaced paths. Then, finally, we come to the Quantum Mechanical Model which is the one accepted today. This model basically vetos Bohr's idea and has a nucleus inside of an electron cloud, which is where the electrons are found.
Answer: ³²P
Explanation:
The radionuclide in question is known as Phosphorus-32. It is an isotope of Phosphorus that is radioactive and has one more neutron than the normal phosphorus does.
Phosphorus does not exist in nature and is created artificially by bombarding the normal stable phosphorus with neutrons. Due to its radioactive nature, it has proven to be useful in the medical industry where it has been used to detect eye tumors as well as in treating some diseases.
