Question

a list of different ions is shown. which combination of ions will result in an ionic bond?
na+
li+
o2-
s2-
f-
so
naf
nao2
lina

Explanation:

Ionic bonds form between a cation (positive ion) and an anion (negative ion).

• \(SO\) is not a combination of the given ions.
• \(Na^{+}\) (cation) and \(F^{-}\) (anion) can form an ionic bond as \(NaF\).
• \(NaO_{2}\) is not a correct combination of the given ions (\(O^{2 -}\) would form \(Na_{2}O\) with \(Na^{+}\) following charge balance).
• \(LiNa\) is a combination of two cations (\(Li^{+}\) and \(Na^{+}\)), no ionic bond can form.

Answer:

B. \(NaF\)
