Explanation:

Step1: Determine the charges of ions

Barium (\(Ba\)) is in group 2 of the periodic table, so it forms \(Ba^{2+}\) ion. Sulfur (\(S\)) is in group 16, so it forms \(S^{2 -}\) ion.

Step2: Balance the charges

For an ionic compound, the sum of the charges of cations and anions should be zero. Let the formula be \(Ba_xS_y\). Then \(2x+( - 2)y = 0\). If \(x = 1\) and \(y = 1\), \(2\times1+( - 2)\times1=2 - 2=0\)

Answer:

E. BaS
