Two electrons are transferred to sulfur from barium to form barium sulfide.
An ionic bond would occur between sulfur and barium.
no it is ionic, because barium is a metal and oxygen (the "oxide") is a nonmetal. Covalent bonds are between nonmetals and nonmetals.
Barium has more energy levels. So it has lesser ionization energy.

barium sulfur. barium sulfide. BaS.
Barium nitrate is Ba(NO3)2
comparison between Airbus380 & Airbus300
Sulfate and barium both have a valence of 2, so that the compound formed between them has the formula BaSO4.
An ionic bond would occur between sulfur and barium.
catecholamine
Barium and tin are both metals, so they would not form any kind of bond.
no it is ionic, because barium is a metal and oxygen (the "oxide") is a nonmetal. Covalent bonds are between nonmetals and nonmetals.
covalent
there is no comparison between them as far as i know
