Question

na+ has completely filled K and L shells. Explain answer for class 9th​

Answer 1

Answer:

Yes, Na⁺ has completely filled outermost shell.

Explanation:

This is because the electronic configuration of Na atom is (2,8,1). When Na loses an electron, it becomes Na⁺ with electronic configuration (2,8). Since the last shell of this Na cation contains 8 electrons, it satisfies the octet rule. Thus, it attains a stable configuration by having a completely filled outermost shell.
