A neutron strikes an atom of uranium-235 to start a fission reaction. A student expresses this situation as 01n+235 92U . Which statement describes why the expression is incorrect?
The atomic number for uranium-235 is in the wrong location. The atomic number for uranium-235 is in the wrong location. The mass number for uranium-235 is in the wrong location. The mass number for uranium-235 is in the wrong location. A neutron should be expressed as 10n , not 01n . A neutron should be expressed as 0 to the 1th power n, not 1 to the 0 power n. A neutron should be expressed as 11H , not 01n .

The correct statement that best describes the mass numbers of the atoms in the reaction 21H + 21H → 42H + energy is: "There are two atoms with mass numbers of 1."
In the reaction, two hydrogen-1 (H-1) atoms combine to form one helium-2 (He-2) atom. Hydrogen-1 has a mass number of 1 (1 proton and 0 neutrons), and helium-2 has a mass number of 2 (2 protons and 2 neutrons).

The statement "The mass number for uranium-235 is in the wrong location" accurately describes why the expression is incorrect.
The correct expression for a neutron is "1n", not "01n". The "0" in "01n" suggests that the neutron has no mass, which is incorrect. The correct notation for a neutron should indicate a mass number of 1 and an atomic number of 0, resulting in "1n". Therefore, the incorrect location of the mass number for uranium-235 is the reason why the expression is incorrect.

I apologize for the confusion. The correct statement that describes why the expression is incorrect is: "A neutron should be expressed as 10n, not 01n."
According to standard notation, a neutron should be represented as "1n", indicating a mass number of 1 and an atomic number of 0. The expression "01n" suggests an atomic number of 1 and a mass number of 0, which is incorrect.
