What is the oxidation state of any pure element in its standard state? a. Pick two elements as examples: one metal and one non-metal. b. For the metallic element in (a), give a compound that contains that element in an oxidized state. c. For the non-metallic element, give a compound that contains that element in a reduced state.
Science behind corrosion-test
Corrosion is defined as an activity that transforms refined metals into more chemically stable forms such as oxide, hydroxide, carbonate, or sulfide. It refers to the slow decomposition of things (typically metals); thanks to chemical and/or electrochemical reactions with their surroundings. Corrosion engineering is the science of preventing and controlling corrosion.

a. Pick two elements as examples: one metal and one non-metal.
b. For the metallic element in (a), give a compound that contains that element in an oxidized state.
c. For the non-metallic element, give a compound that contains that element in a reduced state.
When a molecule loses an electron, that molecule is said to be oxidized whereas when a molecule gains an electron, that molecule is said to be reduced.
The oxidized substances is called as reducing agent whereas the reduced substance is called as oxidizing agent.
Part (a)
Any pure element in its standard state shows 0 oxidation state like O2, H2 etc. Similarly the standard state of Na metal is Na and the oxidation state of it is 0 in its standard state whereas O2 is a good example of non-metal in its standard state with 0 oxidation state.
