Question

directions: write the names of the following ionic compounds:

1. nabr
2. cao
3. li₂s
4. mgbr₂
5. reo

Explanation:

For ionic compounds, the naming convention is to name the cation first followed by the anion.

1. For \(NaBr\), \(Na^+\) is sodium cation and \(Br^-\) is bromide anion.
2. For \(CaO\), \(Ca^{2 +}\) is calcium cation and \(O^{2 -}\) is oxide anion.
3. For \(Li_2S\), \(Li^+\) is lithium cation and \(S^{2 -}\) is sulfide anion.
4. For \(MgBr_2\), \(Mg^{2+}\) is magnesium cation and \(Br^-\) is bromide anion.
5. For \(BeO\), \(Be^{2+}\) is beryllium cation and \(O^{2 -}\) is oxide anion.

Answer:

1. Sodium bromide
2. Calcium oxide
3. Lithium sulfide
4. Magnesium bromide
5. Beryllium oxide
