22. The atomic number of the atom which becomes stable by gaining 3 electrons in 5th sehll is-
(A) 56
(B) 49
(C) 51
(D) 54
Dear Student,
The electronic configuration is stable species 2, 8, 18, 18, 8.
Hence electronic configuration is atom become stable with gaining 3 electrons in 5th shell is
2, 8, 18, 18, 5 and the atomic number is 51.
The electronic configuration is stable species 2, 8, 18, 18, 8.
Hence electronic configuration is atom become stable with gaining 3 electrons in 5th shell is
2, 8, 18, 18, 5 and the atomic number is 51.
Hence option (c) 51 is Correct.
