[单选题]
Which of the followin2bb .6v qxzik;g a)(r5 nju0 gokkre characteristics 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 deloca( n3mcoc: lba4kp9 sc(lized valence electrons in transition elements result in strong m :3cbnsc((9copk4 lmaetallic bonds and therefore high melting points. The delocalized
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
