The metallic character of elements ________.
A)decreases going across a period
B)decreases going down within a group
C)increases going across a period
D)does not change going down within a group
E)none of the above

Question

Quizplus · Accepted Answer

Metallic character decreases going across a period from left to right because the number of valence electrons increases and the effective nuclear charge also increases, making it harder for the atom to give away electrons and form a positive ion. However, going down within a group, metallic character generally increases due to the increasing atomic size and decreasing effective nuclear charge.
