It is True, oxidation is associated with an increase in oxidation number.
An oxidation; reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. Oxidation states are typically represented by integers which may be positive, zero, or negative.
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.

If you're volunteering with Habitat for Humanity, younger people could face challenges working with others that are more skilled because they may not be patient in teaching those that are younger.
In some volunteer situations, volunteers, especially younger ones, could be treated more like employees and doing things that an assistant would do, like fetching coffee.
Some volunteer organizations also have age restrictions.
Youth volunteers may also experience burnout if it's not what they expected from the volunteering experience.
Youth may also find their volunteering activity boring. Volunteering is hard work, and can be a shock when they are told they can't be on their phone, or they can't just stand around and talk to their friends.
Volunteering is incredibly rewarding. You have to go in with the mind set that you are there for others, not yourself. Use it as a learning experience and have fun!
