Step 1:I'll solve this problem following the specified LaTeX and formatting guidelines:
Step 2:: Understand Hydrogen's Electron Configuration
Hydrogen is the first element in the periodic table. Its electron configuration is simple, with only one electron in its first (and only) shell.
Step 3:: Determine the First Shell's Capacity
The first electron shell (K shell) has a maximum capacity of $$2$$ electrons.
Step 4:: Calculate Needed Valence Electrons
Since hydrogen currently has $$1$$ electron, it needs $$1$$ more electron to completely fill its first shell.
Final Answer
Key Insight: - The first electron shell follows the octet rule for the first two elements - Hydrogen wants to achieve a stable electron configuration by having 2 electrons - By gaining 1 more electron, hydrogen can form a stable 1s^{2} configuration
