If only an element's atomic number and weight are provided, the other atomic information that can be determined for a neutral atom is **the number of protons, electrons, and neutrons**.

Here's why:
- The atomic number indicates the number of protons in the atom, which is also the number of electrons in a neutral atom.
- The atomic weight (or atomic mass) can be used to determine the number of neutrons if you know the atomic number. The number of neutrons can be calculated as follows:

\[
\text{Number of neutrons} = \text{atomic weight (rounded to nearest whole number)} - \text{atomic number}
\]

Thus, from the atomic number and atomic weight, you can find the number of protons, electrons, and neutrons for a neutral atom.
