what is the lewis symbol for be^{2+}? select the correct answer below: o :be^{2+} o :be^{2+} o be^{2+} o :be^{2+}
Answer
Answer:
O $\text{Be}^{2 +}$
Explanation:
Step1: Recall Lewis symbol concept
Lewis symbols show valence - electrons as dots around the element symbol. Cations lose valence electrons.
Step2: Determine beryllium's valence electrons
Beryllium (Be) is in group 2, has 2 valence electrons.
Step3: Analyze $\text{Be}^{2+}$
$\text{Be}^{2+}$ has lost its 2 valence electrons. So, there are no dots around the Be symbol for $\text{Be}^{2+}$.
