Question

If only an element’s atomic number and weight are provided, what other atomic information can be determined for a neutral atom?

only the number of protons and electrons

only the valence electrons

only the number of protons and neutrons

the number of protons, electrons and neutrons

(Would anyone who is free help me out with the rest of the questions that I have please?)

Answer 1

Atomic number, by definition, is the number of protons an atom of that element has

Atomic weight is the total mass of the protons + neutrons in an atom

It says in the problem the atom is neutral, so # of protons = # of electrons

With all this in mind, what do you think the solution might be?
