Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Analyze the Electron Configuration
The given electron configuration is $$1s^{2} 2s^{2} 2p^{6}$$.
This represents a complete electron shell configuration.
Step 3:: Count Total Electrons
Total electrons: $$2 + 2 + 6 = 10$$ electrons
Let's count the electrons in each subshell:
Step 4:: Determine the Chemical Symbol
The electron configuration matches the noble gas Neon (Ne). Since the ion has a + 1 charge, this means one electron has been removed.
Step 5:: Identify the Ion
This is the Sodium (Na) ion with a +1 charge, written as $$Na^{+}
Final Answer
1. Chemical Symbol: Na^{+} 2. Number of Electrons: 10 electrons 3. Number of 2p Electrons: 6 electrons Explanation: The Na^{+} ion is formed when a sodium atom loses one electron, resulting in 10 total electrons and maintaining the electron configuration of Neon.
