Question

Which of the following Period 4 elements has the most metallic characteristics?

A) Ca
B) Ge
C) As
D) Br

Answer 1

The scale of most metal characteristics goes from the bottom left-hand corner.

The least metallic is the top right-hand.

So then that means that

Calcium-YES, second column
Germanium-No, to far, in the middle
Arsenic-Non-metal,
Bromine, same for this

Calcium

Answer 2

The correct answer is (A) Ca

Element Ca belongs to s-block of periodic table and rest i.e., Ge, As and Br are elements of p-blocks. Non-metals are located at the top right hand side of the periodic table while metals are on the left hand side. The metals become more non-metallic as we go left to right side of a period in a periodic table. Hence the order for metallic to non- metallic nature will be Ca>Ge>As>Br.
