Which pair of elements can form an ionic compound?
a) two atoms of hydrogen
b) one atom of sodium and one atom of fluorine
c) four atom of carbon and one atom of chlorine
eliminate
d) two atoms of hydrogen and one atom of oxygen

A) acceleration. this seems to be the one that makes sense.

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.
