Question

An element m with electronic configuration 2,8,2combine with separately no3,so4)2 po4)3

Answer 1

The element m is magnesium

When Mg 2+ is cross multiplied with NO3 ^2- it will form Mg(NO3)2

Similarly Mg2+ is cross multiplied with SO4^2- it will form MgSO4

When Mg 2+ is cross multiplied with PO4^3- it will form Mg3(PO4)2
