Respuesta :
That would be the compound Ba(NO3)2. The Barium ion has a charge of 2+ so there are 2 NO3- ions in the formula to produce a neutral compound.
Answer: The chemical compound formed by the combination of given ions is [tex]Ba(NO_3)_2[/tex]
Explanation:
Barium is the 56th element of periodic table having electronic configuration of [tex][Xe]6s^2[/tex].
To form [tex]Ba^{2+}[/tex] ion, this element will loose 2 electrons.
Nitrate ion is a polyatomic ion having chemical formula of [tex]NO_3^{-}[/tex]
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the chemical compound formed by the combination of given ions is [tex]Ba(NO_3)_2[/tex]
The formed compound is an ionic compound.
