Question

The work functions for three metals x,y and z
z are respectively 3'ev', 5ev and 7'ev', then
more reactive metal?
1)Х
2)y
3)z
4)All have same reactivity



PLZ ANSWER ME FASTLY GUYSSS..

​

Answer 1

Answer:

A. all have same relativility

Explanation:

me think so

Answer 2

The more reactive metal is:

(1) X

- The work function is the minimum energy that is required to emit a photoelectron from a metal.

- Less work function means a lesser amount of energy is needed to eject the electrons.

- It means that the metal is more reactive towards the photoelectric effect.

- Hence, metal X with the lowest work function is more reactive.
