The appropriate response is Mg2+. It has the smallest radius the would mean the littlest separation from it's the furthest shell to the core
Since magnesium has one less shell that calcium, Mg would have a little nuclear range. Besides, a particle of a component will have a little nuclear sweep than it's molecule be utilized as a part of its particle frame it has lost a shell
10 because you divide 200 by 20
Answer: To find the energy of a photon you want to use this equation: E=hf
Explanation: E is the energy of the photon in Joules; h is Planck's constant, which is always 6.63*10^-34 Joule seconds; and f is the frequency of the light in hertz.
