Answer 1

If only an element's atomic number and weight are provided, the atomic information that can be determined for a neutral atom is:

the number of protons, electrons, and neutrons.

The atomic number of an element specifies the number of protons, which is also the number of electrons in a neutral atom. The atomic weight (or atomic mass) can be used to approximate the total number of protons and neutrons, with the number of neutrons being the difference between the atomic mass (rounded to the nearest whole number) and the atomic number.
