Explain , in terms of electrons, why the bonding in strontium sulfide , SrS , is similar to the bonding in magnesium bromide, MgBr 2,

Explanation:

The bonding in Magnesium Bromide is ionic bonding. Ionic bonding occurs between metals and non metals, due to the transfer of electrons.

Strontium Sulphide is also an ionic compound. The metal is Strontium and the non metal is sulphur.

In terms of electrons, it is similar to Magnesium bromide in the sense that the metal lost two electrons and the non metal gained two electrons which is the same as in Magnesium Bromide.

i believe that it is a exoplanet

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
