The compound magnesium iodide is a strong electrolyte write the reaction when solid magnesium iodide is put into water

mestny [16]

The reaction for magnesium iodide when put into water is as below

MgI2(s) → Mg^2+(aq) + 2I^-(aq)

when magnesium iodide but into water it dissociate/ ionize completely into Mg^2+ and 2l^- ions. Magnesium iodide dissociate/ionize completely because magnesium iodide is a strong electrolyte which dissociate/ ionize completely into their ions when it is put into water .

Isotopes that decay with a nuclear break-up and emit a significant amount of energy are said to be ________.

podryga [215]

Answer to this is Radioactive isotopes.

Isotopes are the species of the same element having different atomic masses that means the number of protons remains the same but number of neutrons do differ. For example $_{1}^{2}\textrm{H}$ and $_{1}^{3}\textrm{H}$ are the two isotopes of Hydrogen ( $_{1}^{1}\textrm{H}$ ).

Radioactive isotopes are the isotopes which release some kind of energy in the form of alpha particles, beta particles or gamma radiation. Examples of each of the decay processes are :

Alpha Decay: In this decay one alpha particle having atomic mass 4 and atomic number 2 or we can say a He molecule will come out. $_{Z}^{A}\textrm{X}\rightarrow _{Z-2}^{A-4}\textrm{Y}+_{2}^{4}\alpha$
