It forms one, yes. The element in itself is not a bond.
Ionic
BaF2 is an ionic compound composed of a metal (Ba) and a non-metal (F). The bond between Ba and F in BaF2 is considered ionic because the electronegativity difference between Ba and F is large enough for Ba to donate electrons to F, resulting in the formation of positive and negative ions.
Barium sulfide contains an ionic bond, with barium (Ba) donating electrons to sulfur (S) to form a stable crystal lattice structure.
Ba and O are unlikely to form a covalent bond because they have a large electronegativity difference. Ba is a metal with a low electronegativity, while O is a nonmetal with a high electronegativity. This large electronegativity difference makes it more favorable for them to form an ionic bond rather than a covalent bond.
No. One way to tell is that Ba and O are on opposite sides of the periodic table, and Ba is a metal and O is a nonmetal. We can also determine the difference in electronegativity. A difference of >1.6 is generally considered as ionic. The electronegativity of Ba is 0.89 and of O is 3.44. 3.44 - 0.89 = 2.55, so the bond is ionic.

Sodium can form an ionic bond, but sodium (Na) is an element from the alkali metals group.
All of the metallic elements will form an ionic bond with fluorine.
It's an element
Yes, fluorine and sodium will form an ionic bond. Fluorine is a highly electronegative element that will attract electrons from sodium, a highly electropositive element, resulting in the transfer of electrons and the formation of an ionic bond between them.
An ionic bond, where a group 2 element (such as calcium) donates electrons to a group 17 element (such as chlorine), forming ions with opposite charges that are attracted to each other.
Yes, elements k and h can form an ionic bond. Element k (potassium) can donate an electron to element h (hydrogen) to form an ionic bond. The resulting ion pair would be K+ and H-.
An element like sodium (Na) or calcium (Ca) will likely form an ionic bond with phosphorus. These elements typically have one or two electrons to lose, which can be transferred to phosphorus to form a stable ionic bond.
