1. name the following ion: be3p2 (0.5 points) *

enter your answer

1. name the following ion: al3+ (0.5 points) *

enter your answer

Explanation:

For \(Na_2S\), \(Na\) is sodium (a metal with a +1 charge) and \(S\) is sulfide (a non - metal with a - 2 charge). In ionic compound naming, we name the metal first followed by the non - metal with the suffix “-ide”.
For \(Be_3P_2\), \(Be\) is beryllium (a metal with a +2 charge) and \(P\) is phosphide (a non - metal with a - 3 charge). Using the ionic compound naming rules (metal first, non - metal with “-ide” suffix).
For \(Al^{3+}\), \(Al\) is aluminum. When naming cations, we simply name the element followed by “ion”.

Answer:

1. Sodium sulfide
2. Beryllium phosphide
3. Aluminum ion
