Atomic number is same number as the protons...

Neutrons = Mass number - Atomic number ( protons)

Electrons are same number as protons unless the element has a charge..
If it has a charge of +2 it means that the element has 2 less electrons than the neutral atom. If it has a charge of -2 it means that the element has 2 more electrons than what it is supposed to..

A certain shade of blue has a frequency of 7.18 × 1014 Hz. What is the energy of exactly one photon of this light?

I'm assuming you meant 10^(14) instead of 1014
if so, then the energy of one photon will be be 4.76×10^(-19) Joules
