Answer to Question #334067 in General Chemistry for bel

Question

select atoms whose ions have an electron configuration of nd^6(n=3,4,5...).for example , the 2+ ion for V ends the electron configuration with 3d^6

check all that apply;

La

Os

Fe

Rh

Tl

Ti

Answer 1

La [Xe] 5d¹ 6s²

Os [Xe] 4f¹⁴5d⁶6s²

Fe [Ar] 3d⁶4s²

Rh [Kr] 4d⁸5s¹

Tl  [Xe] 4f¹⁴5d¹⁰6s²6p1

Ti [Ar] 3d²4s²

only Fe and Os are atoms whose ions have an electron configuration nd⁶
