There are 30 protons and 30 electrons.
Explanation:
The atomic number gives the number of positively charged protons in an atom or element.
The number of protons is always equal to the number of electrons in a neutral atom.
The positive charge on the proton is canceled by the negative charge on the electron leaving a neutral atom.
