Question

12mg24 how many electrons protons and neutrons are there and how did you find it..please tell

Answer 1

24/2 Mg^2+ means 2 moles of Mg^2+.In one ion,

the number of Protons = 12,

Number of neutrons = 12

Number of electrons = 10.And in 2 mol Mg^2+ there are 2×6.023×10^23 atoms.

So, in 2 moles,Number of Protons =

12×2×6.023×10^23Number of neutrons =

12×2×6.023×10^23Number of electrons=

10×2×6.023×10^23
