It will have 33 protons...........

#### Explanation:

And you should be able to tell me the identity of the element given that you must have a Periodic Table at hand.

Atoms are characterized by the number of protons, massive, positively charged particles, that reside in their nuclei. The number of protons give $Z$, the atomic number: $Z = 1$, hydrogen; $Z = 2$, helium; $Z = 6$, carbon...........$Z = 92$, uranium. Since the protons are positively charged, there must be an equivalent number of electrons, fundamental, negatively charged particles in the NEUTRAL element. The assignment of charge is arbitrary; the point is that electrons and protons have equal BUT opposite electronic charge.
