Q-00001814
What is the electronic configuration of a sodium atom and how does it relate to its reactivity?
1
2, 8, 1; Sodium has a stable configuration
2
2, 8, 7; Sodium has a tendency to gain electrons
3
2, 8, 1; Sodium has a tendency to lose electrons
4
2, 8, 7; Sodium has a stable configuration
Answer and Solution
Answer
C. 2, 8, 1; Sodium has a tendency to lose electrons
Solution:
The electronic configuration of a sodium atom is 2, 8, 1, with one electron in its outermost shell. Sodium has a tendency to lose this outer electron to achieve a stable configuration similar to the noble gas neon, making it highly reactive.
