Answer to Question #160478 in General Chemistry for teeeeeeeeeeeeera

Question

Assuming that the octet rule is obeyed, write out the electron configuration for the ion formed by the element fluorine, F. ..................

This ion is a(n) cation/anion..................... with a charge of .............and has the same electron configuration as the noble gas..............

.

Answer 1

F has 9 electron that is distributed in shell as follows

K = 2 , L = 7 . In K = K shell L = L shell

When 1 electron captured by F it become F^- ( fluoride) and it's configuration looks like nearest nobel gas Ne ( nion) .

F ^- (10 e) : K =2 , L = 8

: 1s² 2s² 2p⁶ ( ans for electron config.)

Anoin, -1 , nion ( ans for second) please place this word serially in the blank.
