What is the general electronic configuration of f-block elements?

Answer 1

Fluorine has the electron configuration: 1s22s22p5, sometimes written as [He]2s22p5

Answer 2

1s2 2s2

2p5

or

[He] 2s2 2p5

Answer 3

The "Noble gas electron configuration," or the condensed electron configuration, for F is

[He] 2s2 3p5.

Answer 4

Fluorine has 9 electrons and the fluoride ion has one more electron (10). So the electron configuration is 2, 8

Answer 5

(n-2)f 1-14 (n-1)d 0-1 ns 2

Answer 6

9F = 1s2,2s2,2p5

Answer 7

1s2 2s2 2p5
