Question

why some metals arr more reactive and other less reactive?

Answer 1

Hii There!!!

Good question... Here is your answer ⤵️

================================

✏️As we know that metals can easily loose electrons as in its valence shell it consists valence number of electrons so it forms electro positive ions or we can say cation.
Hence, they are more reactive .

✏️Here in the periodic table we have 2 types of classified metals.

★That are : Highly reactive and low reactive metals.

•●•When a metal loose electrons rapidly then it will be ' Reactive metals '.
Ex - Sodium
✔️Description : It reacts vigrously in air to lose its electrons and to form a positive ion.

..........................>>>>><<<<<<<.........................

•●•When it reacts slowly with other metals it will be 'Low reactive metals'.
Ex - Palladium

✔️Description: It faces difficuilty to form positive ions and hence, it is less reactive.
