Question

The metallic character of elements
..... in a group from top to bottom.
a. increases b. decreases c. remains constant d. shows indefinite behaviour.
​

Answer 1

Answer:

From right to left across a period, metallic character increases because the attraction between valence electron and the nucleus is weaker, enabling an easier loss of electrons. Metallic character increases as you move down a group because the atomic size is increasing.

Hence option A is correct answer.

Answer 2

Answer:

$\huge \fcolorbox{red}{pink}{answer}$

The metallic character of an element decreases as you move from left to right or bottom to top of the periodic table. This is because atoms have a better ability to gain electrons to fill a valence shell than lose them to and an unfilled shell. In other words, it increases as you go from right to left or top to bottom.
