Step 1: Understand the problem
"Si": :underbrace{dots}_{2}, :underbrace{dots}_{2}, :underbrace{dots}_{2}, :underbrace{dots}_{2}, :underbrace{dots}_{0}
To solve this problem, we need to know the general form of the Lewis dot structure for an element in its neutral state. The Lewis dot structure shows the valence electrons around an atom, with each pair of dots representing an electron. For a neutral silicon atom, the Lewis dot structure can be represented as: Where the first four pairs of dots represent the 4 valence electrons in silicon's electron configuration ([Ne] 3s² 3p²), and the last pair of dots represents the lone pair of electrons that can be added to complete the octet.
Step 2: Explain the reasoning
In this case, there is no need for further calculations or reasoning, as the problem asks for the general form of the Lewis dot structure for silicon. We have already provided this structure in Step 1.
Final Answer
The general form of the Lewis dot structure for silicon is: "Si": :underbrace{dots}_{2}, :underbrace{dots}_{2}, :underbrace{dots}_{2}, :underbrace{dots}_{2}, :underbrace{dots}_{0}
