Question

multiple choice 1 point
which statement explains whether nacl or beo will have a stronger bond?
nacl will have a stronger bond because it has a smaller ionic charge, and a smaller distance between ions.
nacl will have a stronger bond because it has a smaller ionic charge, and a larger distance between ions.
beo will have a stronger bond because it has a larger ionic charge, and a smaller distance between ions.
beo will have a stronger bond because it has a smaller ionic charge, and a smaller distance between ions.

Explanation:

Step1: Recall Coulomb's Law for ionic bonds

The strength of an ionic bond is related to the formula \(F = k\frac{q_1q_2}{r^2}\), where \(q_1\) and \(q_2\) are the ionic charges and \(r\) is the distance between ions. A stronger bond corresponds to a larger force \(F\).
For \(NaCl\), the charges are \(q_{Na^+}= + 1\), \(q_{Cl^-}=-1\). For \(BeO\), the charges are \(q_{Be^{2+}}=+2\), \(q_{O^{2 -}}=-2\). The distance between ions: \(Be^{2+}\) is smaller than \(Na^+\) (\(r_{Be^{2+}}

Step2: Analyze the effect of charge and distance on bond strength

Using \(F = k\frac{q_1q_2}{r^2}\), for \(BeO\), \(q_1q_2=(+2)\times(-2)= - 4\), and for \(NaCl\), \(q_1q_2=(+1)\times(-1)=-1\). Also, \(r_{BeO}Since \(BeO\) has larger ionic charges (\(\vert q_1q_2\vert\) is larger for \(BeO\)) and a smaller distance (\(r\)) between ions compared to \(NaCl\), \(BeO\) has a stronger ionic bond.

Answer:

BeO will have a stronger bond because it has a larger ionic charge, and a smaller distance between ions.
