Arrange the following elements in the increasing order of their metallic character
| Mg, | Ca, | K, | Ge, | Ga |
उत्तर
In the modern periodic table metallic character of the elements increases down the group and the metallic character decreases along the period from left to right.
The position of the given elements in the periodic table are:
Mg - 2nd group and 3rd period
Ca - 2nd group and 4th period
K - 1st group and 4th period
Ge - 14th group and 4th period
Ga - 13th group and 4th period
According to the positions of these elements in the modern periodic table, Ge has the lowest metallic character and K has the highest metallic character. The arrangements of these metals in the increasing order of their metallic character would be Ge < Ga < Mg < Ca < K.
