[单选题]
Which of the following are characterio71s v xtmeu8c:5fk n0ao0c 7vstlw56 // qk vt gqp+0g,u3frustics of transition elements?
I.High melting points
II.Soft
III.Electrically conductive
A. I only
B. I and III only
C. II and III only
D. I, II, and III
参考答案: B
本题详细解析:
The student must recall that the delocaliex*8x +bn4up z7x lz:ized valence electrons in transition elements result in strong metallic bonds and therefore high melting points. The de8 e4:p7z*bx+ lxzn ixulocalized s an d orbital electrons responsible for the strong metallic bonds also make the metals hard and electrically conductive. This question is categorized as easy since the student only needs to recall the basic attributes of transition metals
