Transition Elements 1
Cards in this deck (13)
- 1What are D block Elements?Elements w/ electrons in 3D orbital
btw. group 2-13
Metallic - 2Which elements are the outliers in electron orbital arrangement?Cu and Cr
Have 1/2 filled orbitals, which are stable - 3What are transition elements?D-block elements that form at least 1 ion w/ a partially filled D-orbital
- 4Which are the outliers and why?Sc and Zn
Sc can only lose 1 electron, so can't have partially filled
Zn only ever forms 2+ ions, has complete d orbital - 5What are species in their highest [O] likely to form?Strong [OA]
- 6What is a complex ion?Ion w/ molecule(s)/anions attached to central metal atom via coordinate bonds
- 7What is coordination number?Number of coordinate bonds attached to that metal ion
- 8Draw oxalate iono=c(o-)-c(o-)=o
- 9Bond shape of 6-coordinate complexesoctahedral, 90'
- 10Bond shape of 4-coordinate complexesTetrahedral/Square planar, 109.5'/90'
- 11Draw tetrahedral/square planareh
- 12What elements can form square planar?T.E. ions w/ 8-d electrons in highest E d-orbital shell
Pt2+/Pd2+/Au3+ also included - 13What is the formula of a compound of Chromium+4 water+2 chloride ions[Cr(H2O)4Cl2]+
