<span>d)Electrons need specific amounts of energy to "jump" off an atom and be emitted.</span>
Answer:
3.955*10^48
Explanation:
1 mole of a substance gives 6.02*10^23/6.57*10^24 will give x then cross multiply the answer. is 3.955*10^48
Magnesium bromide= MgBr2
Potassium chloride= KCl
MgCl2 because it is the only option in which a metal appears with a nonmetal. In this case, the metal transfers electrons to the nonmental because the metal has a lower ionization energy.
