Answer:
When fluoride reacts with a metal it forms an F negative ion the flooring Adam has gained an electron and undergone Reduction
Step-by-step explanation:
When fluoride reacts with metal it forms and F negative ion and the fluoride atom gains an electron and undergoes a process what is known as reduction in chemical terms.
This occurs because of the reason that flourine is more electronegative than any of the metal so it gains electron from the metal and thus is said to be reduced. Hence, reduction is the required answer
