Which equation is true of an atom with no elctrical charge A. Number of nutrons = number of protons
B. Number of electrons = number of neutrons
C. Number of neutrons = number of protons + number of electrons
D. Number of electrons = number of protons

Ithink it is letter b, i may be wrong but i think that is the answer

Sorry i don’t know what to do

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
