Question

Show the electuanic transfer in the formation of fillowing .calcium hydride​

Answer 1

Answer:

Explanation:

Na2O- Na has a valency of +1 and Cl has a valency of -2 thus 2atoms of Na proved 2 elecrotns to 1 atome of Cl.Similarly for CaH2 -valency of Ca is +2 and valency of H is -1 ,thus 1 atom of Ca provide 2 electrons to 2 atoms of H
