Answer 1

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**

A neutral atom has the same number of protons and electrons (equal to the atomic number). The number of neutrons can be calculated by subtracting the atomic number from the atomic weight (rounded to the nearest whole number).
