Statement: Reducing agents are mostly non-metals while oxidizing agents are mostly metals.
State whether the given statement is true or false.
A. True
B. False
Solution
To answer this question the periodic properties of the elements from the different groups should be known. The periodic properties have opposite trends between left to right and top to bottom. The elements in periodic tables are arranged in a way that every element of each group shows similar physical characteristics and chemical characteristics.
Complete step by step answer:
A periodic table is a great source of information about the elements and their relation to each other. Changes of different periodic properties. Also, this helps to provide predict the properties of the elements even if they are not be discovered.
In the case of the periodic table from left to right metallic character decreases and non-metallic character increases as well as the electro positivity of the element decreases and electronegativity increases.
As metals are electropositive, they tend to donate electrons. And as non-metals are electronegative, they tend to accept electrons.
According to the electronic method. The species which donate electrons are called a reducing agent and the species which accepts the electron is called an oxidizing agent.
As metal donates electron it is a reducing agent and non-metal accepts electron so it is an oxidizing agent.
So, the given statement is true.
The correct option is A.
Note: Due to the high atomic mass of the bottom elements of this group, the physical state of the bottom elements is solid at room temperature. And due to low molecular mass top elements are in a gaseous state at room temperature. But bromine is in the middle of the group and also the molecular mass of from is not large to be solid as well as low to be gas. Due to this reason, the physical state of bromine is liquid at room temperature
