Question

Give reasons as to why the oxidising power of elements increases on moving from left to right along a period in periodic table.

Answer 1

The oxidising power of elements depends on the tendency to gain electrons which increases from left to right along a period due to increase in nuclear pull.

Answer 2

The term oxidising power refers to the ability to accept electrons. As we move from left to right on the periodic table, the element's size decreases, the nucleus's hold increases and incoming electrons are easily accepted. As a result, the oxidising power of an element increases.
