本题目来源于试卷: Models of Bonding & Structure B.3 The Metallic Model，类别为 IB化学
[单选题]
Which of the following are charac97vy; tmv- a p34ylleuteristic0wbd v: je1cwn7ghc1; i1 ifc dr,9k*os 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 delocalized valence electrons in transition mpr dx78;mf)qgke8l 0elements result in strong metallg p8)em lk0 fd;m7qr8xic 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
