Step 1:I'll solve this problem step by step, following the specified LaTeX and formatting guidelines:
Step 2:: Determine the Atomic Number and Valence Electrons
- Electron configuration is $$1s^{2} 2s^{2} 2p^{4}
- Oxygen's atomic number is 8 - Valence electrons are the electrons in the outermost shell (2s and 2p orbitals) - Oxygen has 6 valence electrons
Step 3:: Understand Electron-Dot Diagram Rules
- Place the element symbol in the center - Distribute valence electrons as dots around the symbol - Follow these rules:
Step 4:
Start with single electrons on each side
Step 5:
Pair electrons when possible
Step 6:
Maximum of 8 electrons around the symbol (octet rule)
Step 7:: Draw the Electron-Dot Diagram
\begin{array}{c}
- Place oxygen symbol (O) in the center - Distribute 6 valence electrons as single dots first \bullet \ O \ \bullet \qquad \bullet \end{array}
Step 8:: Complete the Electron Pairing
\begin{array}{c}
- Pair remaining electrons to create stable configuration \bullet \cdot \ O \ \bullet \cdot \end{array}
Final Answer
The electron-dot diagram for oxygen consists of the oxygen symbol with 6 dots (2 single electrons and 2 electron pairs) surrounding it, representing its 6 valence electrons.
